From a university student to a chief academician

Chapter 166 Invisible Smoke
in the laboratory!

Ye Fei looked at the ten people under him.

There were 500 people who came to join Ye Fei, and Ye Fei divided these 500 people into ten groups, each with 50 people.

Ye Feidao: "Our current work is to develop a brand-new ultra-wideband pulse technology."

Uncarrier is called ultra-wideband, and uncarrier pulse technology is called ultra-wideband pulse technology.

"The so-called ultra-wideband pulse technology is the waveform of ultra-wideband."

"Based on the research on ultra-wideband pulse technology at home and abroad in recent years, as far as I know, the world's most advanced ultra-wideband pulse technology is researched through orthogonal basis functions."

Whether it is ultra-wideband pulse technology, or the search for new pulses.

It is all researched and searched through mathematics.

"But I think that the orthogonal basis function is not perfect for the study of pulses."

"The most perfect is through the Gaussian derivative function."

Everyone was noisy when they heard it, discussing softly with each other.

Ye Fei didn't stop him, he didn't say what he said, and Ye Fei believed that scientific research needs to have opposing voices.

Only with opposing voices can we find the most suitable research direction from many ideas.

After a while, a person said: "Professor Ye, using orthogonal basis functions to study ultra-wide pulse technology has been scientifically verified. For decades, scientists have discovered that orthogonal basis functions are the most suitable for researching communication technology."

"And you propose Gaussian derivatives, I wonder why."

Orthogonal basis functions are a common mathematical tool. Its algorithm can find mutually orthogonal basis functions in a high-latitude space, so that its basis functions can be used to represent arbitrary complex data.

It can be used in the field of signal processing, machine learning...

Ye Feidao: "As we all know, orthogonal basis functions belong to the field of linear algebra, and linear algebra is usually used to study space and latitude."

"In this regard, I admit that the orthogonal basis functions are indeed very applicable to the field of communication."

"But last year, I found in a research that using the Gaussian derivative function is more suitable than the orthogonal basis function."

"Orthogonal basis functions are used to calculate the spectrum utilization and operation time of pulses through algorithms."

"The orthogonal basis function has strong flexibility and high utilization rate in terms of pulse."

"The Gaussian derivative function, in terms of pulse, has a higher utilization rate than the orthogonal basis function, with half the utilization rate, and the orthogonal basis function has a 30% utilization rate."

"In terms of flexibility, it can find the optimal waveform and perform MATLAB simulation on the linear combination of normalized Gaussian pulse derivatives."

"So, the Gaussian derivative function has the same characteristics as the orthogonal basis function, and it is even better than it."

"Because of this, I said that it is more appropriate to use the Gaussian derivative function than the orthogonal basis function."

After listening, everyone looked at each other suspiciously.

Although Ye Fei talked about the Gaussian derivative function in a hype, but they haven't done the experiment, so they are not sure whether what Ye Fei said is true.

Ye Feidao: "In this way, I will write a basic formula for studying ultra-wideband using Gaussian derivative functions for you to see. After reading it, you will be able to determine the advantages between it and orthogonal basis functions."

Everyone nodded and said, "Okay!"

Ye Fei found a pen and paper, and wrote down a set of formulas on it.

"Look, everyone!" Ye Fei handed them the paper with the formula written on it.

Everyone looked at the formula and discussed with each other.

One person said: "Look at this set of formulas. If you put them in, you can determine the signal whose ratio of broadband to center frequency exceeds 50%."

The ratio of wideband to center frequency of UWB is more than 20%.

And this formula can make the ratio of broadband to center frequency exceed 50%, which means that the network signal researched by this formula is very high.

"Also, the broadband upper limit can reach 200GHz."

"This means that the upper limit of research is even higher, and it is also very suitable for Li-Fi's requirements for network speed."

The network speed of Wi-Fi6 is 10GHz, and the network speed of Li-Fi is 100GHz.

After a while, everyone handed the paper to Ye Fei and said, "Professor Ye, your idea is correct. We agree with you to use Gaussian derivative function to study ultra-wideband pulse technology."

Ye Fei smiled and said: "Don't worry, we will definitely be able to develop ultra-wideband pulse technology."

"En!" Everyone nodded.

Academician Ning's office!

Ye Fei knocked on the door and walked in after hearing a call to come in.

Academician Ning saw Ye Fei walk in and said with a smile, "Professor Ye, please sit down!"

After Ye Fei sat down, Academician Ning asked, "How is it? Have you finished talking with your team?"

"The talk is over." Ye Fei said: "We finally decided to use the Gaussian derivative function to study ultra-wideband pulse technology."

"Gaussian derivative function?" Academician Ning asked in surprise, "Didn't you use an orthogonal basis function?"

Ye Fei shook his head: "No, because I found through research that the Gaussian derivative function is more suitable for researching communication technology than the orthogonal basis function."

Academician Ning said with a smile: "No doubts, no doubts, I don't ask why you use the Gaussian derivative function, I just want the result."

"I don't care what method you use, as long as you develop ultra-wideband pulse technology."

Ye Fei smiled and said, "Don't worry, I will definitely research it."

Academician Ning said: "Do you need any help from me?"

"Funds, supercomputers, talents."

"The 500 people who follow me now, I'm not sure how capable they are. If you need some talents in the future, I hope you can provide them to me."

"Yes!" Academician Ning said: "No problem, as long as you need any talents in the future, I can provide them to you."

"I don't have it here, I will dig it from other places through my contacts."

"Moreover, this project is a national key project, and many people above are staring at it."

"As long as there are talents in our country, they will be dug for you."

"I'll give you as much money as you need."

"The supercomputer uses the supercomputer of Rongcheng Supercomputing Center."

The Rongcheng Supercomputing Center was built in the past two years and is located in the southeast corner of Xinglong Lake in Tianfu New District.

"I will call the supercomputing center after that, and go to them directly when you use it, and they will let you use it."

"Okay!" Ye Fei smiled and said, "Then I have no other requirements."

Academician Ning said: "Look, it's already past ten o'clock, you're hungry!"

Ye Fei rubbed his stomach, and smiled embarrassedly: "If you don't tell me, I haven't realized it yet, I'm really hungry."

Ye Fei was busy all day, and even forgot about being hungry.

"I didn't think well, let's go, let's go to eat."

After speaking, they stood up and walked outside.

The school cafeteria was already closed after ten o'clock.

So Ye Fei and the others went to eat at a restaurant near the school.

After eating, the two returned to their respective residences to rest.

The next day, in the lecture theater!

Ye Fei gathered all the team members, and all 500 people came together.

Ye Feidao: "After I communicated with the team leaders of each group, it was finally decided to use the Gaussian derivative function to study ultra-wideband pulse technology."

"I think you all know this!"

Everyone nodded. They all knew the news last night.

At first they wondered why Gaussian derivatives were used.

After the group leader's explanation, they knew why Gaussian derivative function was used.

Indeed, it is more appropriate to use Gaussian derivative functions to study the communication field than orthogonal basis functions.

Ye Fei said: "Since you all know, I won't explain again, but let me talk about my research habits."

"For all the research I participated in, as long as it is the research I lead, I will tell the research direction at the beginning, and the main formula is also deduced by me alone."

"Woo..." Everyone looked at Ye Fei in surprise.

No, you can tell the research direction from the very beginning?

You know the research direction before you start the research?

According to common sense, the research direction can only be known by constantly exploring in the research.

Instead of knowing the research direction before starting the research.

Unless the research is simple, or the research has been done before.

But now they are studying ultra-wideband pulse technology, which is difficult to study, and they have never studied it before.

Therefore, it is very unreasonable for Ye Fei to say the research direction at this moment.

What is even more unreasonable is that Ye Fei has to deduce the main formula by himself.

The main formula is the most difficult part of the research, and Ye Fei has to deduce it by himself?
You are human, not god.

Everyone looked at Ye Fei suspiciously.

Ye Fei didn't care about the eyes of the crowd, this was the first time Ye Fei had contact with them, and many of Ye Fei's behaviors seemed unbelievable to them.

But Ye Fei did it easily.

It doesn't matter if they suspect Ye Fei now, time will tell.

Ye Feidao: "The research is divided into three parts."

"First, determine the research principle."

"Second, the pulse of the ultra-wideband system."

"Three, simulation results and analysis."

"Let's start with the research principle."

"The first thing we need to know is the concept of ultra-wideband."

"The second is radiation masking of UWB signals."

"Let's talk about the concept of ultra-wideband first, and now for ultra-wideband..."

For a whole day, Ye Fei held a meeting with the team members, explaining to them in detail how to do the research.

Many people said: "It's been said in such detail, it's just a matter of teaching us how to research it. Ye Fei won't have studied ultra-wideband pulse technology!"

They found that what Ye Fei said was too detailed, as if he had personally experienced the research of ultra-wideband pulse technology.

In fact, Ye Fei has personally experienced the research of ultra-wideband pulse technology.

Rather, Ye Fei has come into contact with too many scientific researchers over the years and absorbed too much inspiration.

A lot of research, even if Ye Fei has not personally experienced the research.

But as long as Ye Fei researches, many inspirations burst out in his mind instantly.

Because of this, when Ye Fei told them about the research of ultra-wideband pulse technology, they sounded like Ye Fei had experienced it himself.

Of course, after listening to Ye Fei's detailed explanation, they already knew how to study next.

They are also very easy to study.

This is equivalent to Ye Fei telling them the answer, and then they just copy it.

Of course, the difficulty of copying and copying homework is naturally different.

But it must be countless times simpler than their previous research models.

Ye Fei said: "Okay, that's all for today. If there is anything to add in the future, I will call you again, and the meeting will end!"

After speaking, Ye Fei got up and left.

The next day, they began to invest in research.

This time Ye Fei also did it himself.

In the past, after Ye Fei informed the team members of the research direction and main formula, he rarely intervened in the research of the team members.

Ye Feixin said: "It's not good if you don't get started, this research is too important."

"Wi-Fi7 can restrict 5G, so Li-Fi should be researched before Wi-Fi7 comes out."

Not to mention the importance of 5G, but North America is researching Wi-Fi7.

If Wi-Fi7 comes out, then nothing can resist Wi-Fi7.

At that time, something big will happen, and the consequences will be very serious.

Because of this, Ye Fei attaches great importance to Li-Fi research.

Even more important than asymmetric encryption algorithms.

After all, there is no sense of urgency in the research of asymmetric encryption algorithms.

And Li-Fi research has a sense of urgency.

Ye Feixin said: "Beili Country has been developing Wi-Fi 7 for six or seven years, and it should come out soon."

"I must develop Li-Fi before Wi-Fi7 comes out."

Beili Country, Wi-Fi Alliance, Wireless Communication Technology Research Institute!

director's office!
Sierra Berger is chief scientist at the Wireless Communications Technology Institute.

He is an honorary professor of electronic communication at the Massachusetts Institute of Technology and a member of the North American National Academy of Sciences.

Once won the Marconi International Research Foundation Award.

The Marconi International Research Fund Award is the highest award in the field of communication, which is equivalent to the Nobel Prize in the field of communication.

Here is the difference between a Fellow and an Academician.

In North America, the fellowship is limited, and the academician is lifelong.

The status of a Fellow is one level lower than that of an Academician.

Berger said excitedly: "Dean, in nearly a year, Wi-Fi7 will be developed."

"The research on Wi-Fi7 has cost us countless efforts, and now it is finally going to succeed."

The dean smiled and said, "Very good, Berger, I will report your contribution upwards when Wi-Fi7 is successfully developed."

"At that time, if you run for the dean of the Massachusetts Institute of Technology, the above will help you, and 100% let you pass."

"Thank you!" Berger laughed. "I'm sure I will succeed."

"As long as Wi-Fi7 comes out, 5G will be greatly limited."

"Yes!" The dean nodded: "Even if Xia Guo has 5G, but we have Wi-Fi7, we can limit the speed of 5G."

"Yeah!" Berger nodded: "By the way, Xia Guo heard that someone is researching Li-Fi. Is this news true?"

The dean said disdainfully: "It's true, Li-Fi has a lot of disadvantages, so what if it is researched."

"Things that cannot be popularized are useless to research."

"I really don't understand what these people are doing with Li-Fi."

"Yeah!" Berger nodded.

Neither of them would have thought that Li-Fi would be a devastating blow to Wi-Fi7.

In their minds, Li-Fi has a fatal flaw, and it cannot be popularized after research, which means that research is useless.

Berger said: "I heard that there is a person named Ye Fei in Xiaguo who developed an asymmetric encryption algorithm. Is this true?"

The communication field belongs to the computer field, and the asymmetric encryption algorithm belongs to the blockchain field.

The blockchain also belongs to the computer field.

Therefore, there is an intersection between communication and blockchain.

"Yeah!" The dean nodded: "This news is true, and many people in the computer circle know it now."

"But his research is only the theoretical part, and the application part will not come out until several years later."

"I heard that this person named Ye Fei is only 26 years old this year."

"Yes." The dean said: "Many people compare him with V God of Ethereum, saying that he is another great child prodigy of the blockchain."

Berger said: "Mochizuki Shinichi's consensus mechanism, Xia Guoshutu Blockchain Research Institute's distributed ledger, Ethereum's smart contract, plus Ye Fei's asymmetric encryption algorithm."

"What do you think will happen if they work together?"

"It is possible to start the era of Web3.0."

"Plus 5G support!"

The dean said in horror: "That will be the end of the world!"

Mochizuki Shinichi, Treemap, Ethereum and Ye Fei.

They can start the era of Web3.0.

5G is the energy source of Web3.0 and supports the development of Web3.0.

But in this changing situation that changed the world, the North Li country did not participate in any way.

In particular, Xia Guo participated in three fifths of it.

For Beili Country, this is really the end of the world.

Mochizuki Shinichi is from Dongying, the tree map is from Xia, Ethereum V God is from Northern Russia, and now lives in Canada, Ye Fei is from Xia, and 5G is from Xia.
