Chapter 130: Smart Antenna!
"Secretary Sun, don't worry, even if Aida Electronics Company goes bankrupt, I still have shares in Samsung Motor Company, and I won't give you any less money. Xue Yunlong received a call from Sun Yaohe, and he suppressed the anger in his heart and said.
In the past few days, he has received a lot of calls from people, all of whom want to get back their money, and they are all related to officials, and he is also very annoyed.
"I think that now Aida Electronics Company has simply shut down, and the automobile assembly line in Yizhou has been completed, which is much faster than engaging in electronics manufacturing. Rong Xinhai said.
"Yang Shao, it's been more than a year, how much have you earned doing this?" Fang Youmin asked.
"If it weren't for that bastard to get in the way, I wouldn't have a problem making hundreds of millions a year, and now I'm still losing more than 100 million fucking dollars!"
For this matter, Xue Boxiong also reprimanded Xue Yunlong fiercely, and at this time he couldn't wait to cut Yang Jie with a thousand knives!
"This Yang Jie is really too deceitful!" Wu Minxiu said with a cold face.
"Just find someone on the road to kill him, it's a hundred!" Lai Bingxian said coldly with a fierce face.
"Don't!" Wu Xiumin was taken aback, she stared at Lai Bingxian tightly and said: "This is in Huaxia Kingdom, this kid is highly respected by Governor Luo, and Lan Sheng said that the head of the Central Committee knows him, and none of us can get rid of him if he is moved now." ”
"Then we just endure it like this, and there is no way to deal with him?" Lai Bingxian said indignantly.
"Don't worry, Lan Sheng is secretly planning now, when the time comes, he will bring down Luo Binghuan, the tree will fall and scatter, and there will be no one to protect him, and he will not let us step under his feet!" Wu Minxiu said slowly, with a chill flashing in his eyes.
The matter of Aida Electronics Company was noisy by the major media, but Yang Jie did not take this matter to heart, he knew that this time Xue Yunlong's Aida Electronics Company was completely finished, and he was more willing to focus on technology research and development than this.
Hu Yibo and others have now entered Huaxing Technology Company in advance, and now lead two R&D teams to be responsible for the research and development of processors and graphics processors, he is also very close to this, but he no longer needs to design it himself, he only needs to put forward the functional modules of the processor and the requirements, and the specific process Hu Yibo and others have been able to start on their own, which also frees him from the tedious research and development process.
Not only these teams led by Hu Yibo, but also other R&D personnel of Huaxing Technology Company have also grown rapidly.
Yang Jie himself was the world's top microelectronics scientist in his previous life, with rich experience, and these engineers around him learned a lot of technical experience from him, and he was directly involved in electronic engineering projects, so he naturally grew very fast.
At noon that day, Yang Jie also rushed to a test site on the outskirts of Huaxing Communication Equipment Company, which is a wasteland, surrounded by mountains, and there are no residents nearby.
Now the dark wave laboratory and other test laboratories of the communication equipment company are under construction, and it will take another year or two to complete the completion, and Yang Jie cannot let the research and development wait for the completion of these laboratories before starting, so he chose such a remote place to do the test.
The company bought a few hundred acres of land here, and made a test base after leveling.
When he arrived here, Yang Jie also saw the antenna tower standing high there, carrying several cylindrical antennas.
This is the technical solution of the smart antenna proposed by Yang Jie as early as last year, and Luo Zhen and Lin Ping and other technical backbones also organized a special R&D team to overcome the technical problems of the antenna.
Yang Jie has not been a shopkeeper in these days, and he has also provided a set of algorithm models on the adaptive algorithm, which has greatly promoted the research and development progress of smart antennas.
This smart antenna system is the same as the mode of satellite communication, and these foreign telecommunications giant companies use or are developing TDMA, FDMA, CDMA antenna mode is different, the smart antenna uses space division multiplexing (SDMA) mode, the use of signal in the direction of the propagation path, the delay diffusion, Rayleigh fading, multipath, channel interference to reduce the impact, the same frequency, slot signal differentiation, combined with other multiplexing technology, maximize the effective use of spectrum resources.
This technology was first concentrated in the field of radar and sonar signal processing, and was introduced into the field of military communications after the 70s, and two years later the Telecommunications Science and Technology Research Institute of the Ministry of Posts and Telecommunications of Huaxia provided the TD-SCDMA standard to the International Telecommunication Standards Organization.
Officials of the Ministry of Information Industry also have high hopes for this standard, and also let Ericsson, Nokia and other telecommunications equipment manufacturers in the Chinese market as a condition, requiring them to give support, and the vast majority of international communication equipment manufacturers also expressed support.
Although TD-SCDMA has certain advantages in this 3G standard, the Telecommunications Science and Technology Research Institute has proposed that this communication standard has not been able to solve the technical shortcomings of continuous related technology, and can only distinguish cells through 9 frequency points, with only 1.6M bandwidth per carrier, resulting in an air interface rate much lower than CDMA and CDMA2000.
According to the actual test, the TD-SCDMA network deployed by China Mobile is worse than the A network and CDMA2000 network in terms of network speed and stability.
Huaxia Mobile is really not very optimistic about such technical standards, due to the support of the state, it is also a clear requirement to promote this communication standard, requiring manufacturers to be compatible with TD-LTE fourth-generation communication standards when networking, and the fate of TD-SCDMA has long been doomed.
Later, when Huaxia Mobile launched the 4G communication standard, it was clear that the 4G voice service would be reduced to the 2G network built by itself instead of the 3G network, and TD-SCDMA was abandoned.
With the advent of the 4G era, China Mobile will no longer invest in new TD-SCDMA construction, and will gradually transition the TD-SCDMA users developed in the past to the 4G network.
The TD-SCDMA network may be the shortest-lived generation of 3G network in history, and it has survived for five years from the time it was licensed to 10,000 base stations.
Yang Jie is proficient in communication technology, of course, he came up with a lot of solutions when designing this program, especially after the Chinese New Year, the military transferred hundreds of electronic communication engineers from many research institutes to join Huaxing Communication Equipment Company, which includes more than ten technical experts, which can be regarded as an indirect reward for the male protagonist.
It is gratifying that this group of experts and technical teams has rich R&D experience, which has greatly enhanced the R&D strength of Huaxin Communication Equipment Company.
The R&D project that Yang Jie had always wanted to start immediately started.
With the promotion of several experts who have been developing military communications and radars, a few months have passed, and significant progress has been made in smart antenna technology, and Yang Jie also rushed over immediately.
When approaching the base, Yang Jie also saw a van running at high speed along a ring road built outside the base.
Luo Zhen and several middle-aged people also came up, all of whom were military experts involved in the development of smart antennas.
Yang Jie got out of the car and shook hands with Luo Zhen and several experts with a smile: "I heard that the smart antenna test results are good?"
"Yang Shao, the algorithm model you provided is really wonderful, and it has made a huge breakthrough in smart antenna technology in China all of a sudden. The person who spoke was Lei Mojun, the chief engineer of the smart antenna, who had participated in the design and development of many military radars and had extremely rich experience.
He knows very well that the design scheme and algorithm model proposed by Yang Jie will definitely make the military improve to a very high level in radar and satellite communication when applied to military radar, and he can't understand how Yang Jie mastered these technologies, and he can only be described as a genius.
Yang Jie said with a smile: "I just provide some technical solutions, and the specific things are all completed by Chief Engineer Lei and everyone." ”
He knew that after Lei Mojun joined the company, he also quickly made samples of smart antennas, and used a lot of mature military technology in the middle.
After a while, the test vehicle, which was converted from a van, stopped in front, the back door of the car opened, and several technicians also got out of the car sweating profusely.
There was no air conditioning in the modified test car, and now that the weather is hot, the inside of the cabin is even hotter, and it is even more stuffy to stay in it for testing.
"Yang Shao, Mr. Luo, Chief Engineer Lei, we just tested the speed of more than 100 miles, around the field a few times, the communication signal is very stable. The technician in charge of the test said excitedly.
