The 500 mathematical geniuses who accepted the invitation of Neutron Star Information Technology Company were introduced by their mentors, or they came after hearing about the company's management methods and advocating scientific and technological innovation.

For people who like to bury their heads in research, they can't stand other people's criticism.

And the relaxed management style of Neutron Star Technology Group is simply more attractive than doing research alone.

You can apply for R&D funding, there are the best prerequisites, and the company doesn't even care what you do!

Is there a better company than this?

Among them, Yun Zhiwei, Xu Chenyang, and Zhang Wei all wanted a relatively quiet environment to do mathematics, and Wang Xiaowei, who was only a teenager, kept twisting the thirteenth-order Rubik's Cube, was brought over by Xu Chenyang.

"If there is no opinion, the communication department of Neutron Star Information Technology Company has been officially established!" Zhong Zixing asked at the five hundred mathematical geniuses in the conference room.

"No comment!!"

"Communication technology hasn't been tried yet, but it sounds interesting!"

"Interested in this challenge will come to take on this challenge."

"Eh, Senior Zhong...... We all know that if you want to study 5G, what kind of code do you plan to use? ”

"LDPC or Turbo, or Polar?" Zhong Zixing, who was also from Tsinghua Garden, chewed gum and blew bubbles and asked.

Of the three codecs, two are the mainstream of the current communication standards!

LDPC code is the abbreviation of low-density parity code, which was proposed by Gallager in his doctoral dissertation as early as the 60s of the 20th century.

Among them, the 5G standard of the communication giant Qualcomm uses this code.

It is worth mentioning that most of the 4G standards also use low-density parity checksums.

Turbo code is a cascading code first proposed by Claude Berrou et al. in 1993.

This is the kind of code that the French telecommunications giants mainly promote.

The Polar code, also known as the polar code, was first proposed by Professor Erdal Arıkan of Bilken University in Turkey at the International ISIT Conference on Information Theory in 08.

This is the kind of code that Huawei uses!

Polar is also the only method that can be rigorously proven to reach the Shannon limit.

The coding schemes of these control channels are excellent, and the first two have been deeply cultivated for several years and have a strong foundation, but if you are biased, Zhong Zixing will still choose Polar code.

If nothing else, it's because Huawei is also studying this kind of coding.

However, no matter how good these codes are, Zhong Zixing does not want to use them until there are no decisive criteria.

Because in his opinion, even if these yards reach the Shannon limit, they are still a bit rudimentary for the distant future.

The maximum transmission rate for error-free transmission on a channel where random bit errors occur has not improved much other than to confirm the conclusion that the bandwidth is limited.

It's just that the breakthroughs made by generations of communication technology in quantitative change cannot achieve qualitative change.

In order to control the standard and not be surpassed, it is necessary to fundamentally solve the problem and develop a stronger communication technology at one time, so that others cannot catch up with the technology no matter what.

Of course, it is not quantum communication, the cost is too great, and there is no condition to implement a quantum communication scheme at present.

"We don't use these three codes, and we have to do it until no one else can surpass it...... But before that, I want to go to the deep city and meet an old man who deserves our respect! ”

Zhong Zixing thought of Hua Wei, the old man who would still show a smile in front of the media even if his daughter was forcibly imprisoned by other countries in the future, claiming that his daughter was okay and people didn't have to worry.

......

The communication technology department of Neutron Star Information Technology Co., Ltd. was officially established.

Because there was no unified technical task to tackle, Zhong Zixing let this group of geniuses move freely, study mathematical problems, and wait for his answer.

He pondered what kind of communication technology he wanted to use to complete the next generation of communication and transmit information in space in real time and indiscriminately......

Quantum communication was first excluded because even if this technology was developed, it would not be suitable for large-scale commercial use under current conditions.

There is too much knowledge in my mind, but it is rarely technology, most of it is theory, and all of it needs to be understood and digested by myself before I can use it.

"Let's study the rudiments of solar broadcasting first?" Zhong Zixing's eyes lit up when he thought of an excessive communication technology before civilization initially entered space and before the interstellar age.

Solar broadcasting is divided into three phases, and even if only the first stage of solar broadcasting is studied, it far surpasses 5G in terms of information transmission efficiency and speed.

In the future, we can continue to study based on this prototype, and until humans conquer the entire solar system, this technology will continue to be used and will not become obsolete.

Zhong Zixing thought about it seriously, and there was a sudden knock on the office door.

"Mr. Zhong...... I have something to report! Chu Wangduan, who replaced Wu Wanrou and was promoted to the manager of the personnel department of Pan Entertainment Group, walked in.

"The names of all technical products are named after the stars of the galaxy, and the solar broadcasting technology is called solar communication...... The node is called Taiyin! Zhong Zixing clenched his fist and tapped his palm, making a decision, he came back to his senses and looked up and asked.

"By the way, what did you come to me to report?"

Chu Wangduan's face was a little unpleasant, which was completely different from the usual smile that always greeted people with a smile.

"The recruitment of Pan Entertainment Group is going very smoothly, in addition, Yao Xiaoguang, the manager of the game department, asked me to come over and invite you to come over, the loopholes in the glory of kings have been cheated!"

"Huh? Plug? Zhong Zixing's face changed, and he immediately frowned, "This matter hasn't been resolved yet?" ”

When he went to the United States, the loophole incident had already begun, but he didn't expect that a week had passed and it hadn't been dealt with.

"There has been a commotion on Weibo, countless players have recorded videos @ the official blog of the company's game department, and the technical department can't solve it for the time being, and even can't find the source of the plug-in, I heard that there are hackers with strong skills who have intervened!" Chu Wangduan's face was full of worry.

The technology of Neutron Star Pan Entertainment Group is very strong, and with the help of information technology companies, this problem has not been solved, which shows that there are talented people behind this matter who do not want to make Neutron Star Pan Entertainment Group better.

After all, the strength of the Orion game engine and game platform will shake the foundation of all large companies in China that depend on games for a living.

Small studios are fine, and the channel with Neutron Star will develop better, but for large companies, they don't want to see a sudden addition of companies in the game market that can determine their survival.

Zhong Zixing's face was not good-looking, he never thought that just after reaching a cooperative relationship with Facebook, the e-sports league was about to be held, and the game platform was about to be released abroad, there would be such a thing.

Don't think about it, the ones who have the ability to do this must be those domestic game giants.

"Let's take a look!"

Zhong Zixing got up and took the lead towards the game department downstairs, with Chu Wangduan following closely behind.
