Application of Software Radio Technology in Communication Navigation System

Youbin Zhuang, Bo Zhu, Yang Tang, Haifeng Luo, Xiaogang Liang

Abstract

In order to improve the communication and navigation system of helicopters,the author proposes the application of combining software radio technology into the communication and navigation system.Firstly,the basic idea and architecture of the system are analyzed,and the key technologies of the system are listed.Through analysis,software radio can well meet the multi-channel,multi-service,multi-user and comprehensive control technology of helicopter communication and navigation sys-tem.However,the RF front-end has extremely high requirements on the sampling speed and accuracy of the system,which are diffi cult to meet by existing processors and digital-to-analog converters,therefore,the radio frequency cannot be completely soft-ware-based,and it can only be digitalized at the intermediate frequency.The development of technology requires a process,and many aspects cannot be achieved in one step,in the process of development,development problems will be encountered,when encountering these problems,you should better correct your mentality,the problem should be analyzed from the root cause,and the root cause should be solved,the current development trend is very correct.We must go on steadily and steadily step by step,only in this way can the industry develop better,i believe that even greater achievements will be made in the near future.

Keywords
