Research On Network Coding Technology In 5G Mobile Network

In recent years,mobile communication has improved with a stepped speed,which has brought great changes to people's way of life and social communication,and also promoted the development of social economy.Meanwhile,people have also been trying their best to develop higher performance mobile communication networks than ever before.At present,the latest fourth-generation mobile communication systems network has been unable to meet the demand of high data rate and high transmission rate in the future,researchers have learned about the latest research on the needs and key technologies of fifth-generation mobile communication systems at various domestic international research organizations,and the research on the fifth generation mobile communication system has been carried out in the industry.However,the throughput and transmission reliability of the networks is one of the important problems that the fifth generation mobile communication system has to consider at the beginning of design.It is a valuable job to study how to increase the throughput and reliability of the network.In view of the above problems,this paper studies the principle of network coding technology,uses the network coding technology and polarization codes in channel coding to improve the throughput of network and the reliability of network transmission process.On the issue of improving network throughput,first describe the transmission process between service gateways and user terminals in a fifth-generation mobile communication system network,and give a structural diagram of the transmission between them.It can be seen in this structure,the throughput of the network has the possibility to improve through some kind of technology.In order to change this situation,this paper chooses network coding technology to improve the network throughput,and compares it with the traditional route forwarding method.It is proved theoretically that in the same transmission rate,the throughput of network coding using the network coding technology will be lager than that of traditional transmission network,which the same conclusion can be obtained through the simulation results.In this paper,the use of polarized codes as an improvement to improve the reliability of the system is proposed.Simulate it in Gaussian channel and binary continuous delete channel.The simulate results show that the polar code can meet the requirement of improving system reliability both in Gaussian channel and in binary continuous delete channel.The research content of this paper shows that the application of network coding improves the throughput performance of the whole content structure.The application of polarization code improves the reliability of the communication system.The results have mobile reference value for the research and development of 5G requirements in the future.
