摘要
针对卫星导航系统现代化的需求,采用高效的编译码技术有利于提高导航系统的工作性能与可靠性。研究了BCH码、卷积码和低密度奇偶校验码(LDPC)这3种常见的信道编码,对其编译码方案进行了简要介绍,仿真比较了其编码增益,对不同参数配置下编码性能进行了分析与比对。依据仿真结果,综合编译码复杂度、电文设计等需求,提出了适用于北斗RDSS系统现代化发展的信道编码的方案,为北斗系统信号体制设计提供了分析思路和设计参考。
In view of the demand of satellite navigation system modernization,the application of high-efficiency codec technology is favourable to improve the operation performance and reliability of navigation system.This paper studies such three common channel coding methods as BCH code,convolutional code and LDPC code.The codec scheme of these three methods is introduced briefly,the coding gain is simulated and the coding performance in different parameter configuration is analyzed and compared.Based on simulation results and combined with codec complexity and message design,this paper proposes a channel coding scheme suitable for Beidou RDSS system modernization and provides analysis idea and design reference for Beidou system signal system design.
