摘要
针对近年来导航信号中出现的新的调制方式及扩频码结构,分析了影响码跟踪精度的因素和调制方式及扩频码对码跟踪的影响。基于Matlab仿真,比较了二进制相移键控(BPSK)、二进制偏移载波(BOC)、复合二进制偏移载波(MBOC)和二进制编码符号(BCS)调制方式及不同扩频码结构对码跟踪精度的影响。
According to the new modulation and spreading code in navigation signal in recent years,this paper analyses the factors that influence precision of code tracking and the effect of modulation and spreading code on precision of code tracking.And it compares the effect of BPSK,BOC,MBOC and BCS modulation and different structures of spreading code on precision of code tracking based on Matlab simulation.
