| 摘 要： | 码相关参考波形（CCRW）技术是一类通过改变码跟踪环路的本地参考信号波形来改善GNSS接收机多径抑制性能的技术的总称.本文对五种波形的CCRW技术在BOC信号接收中的应用及其码跟踪性能进行了分析仿真,其中三种技术为首次应用于BOC接收机中;文中提出了三种基于多径误差包络的多径抑制性能评估指标,并根据这些指标对五种波形的CCRW技术应用于BOC信号时的多径抑制性能进行了定量的比较,得出的结果为针对BOC信号接收机的多径抑制技术设计提供了指导方向.

| Abstract: | CCRW (Code correlation reference waveform) techniques are one kind of techniques in GNSS which improves the multipath mitigation performances of the code tracking loop by changing the local reference code waveform. Five CCRW techniques are applied in GNSS BOC signals receiving and their performances are analyzed based on the investigation on the discriminators. Three among these CCRW techniques are used in BOC receivers for the first time. Also this paper proposes three criteria for multipath mitigation cap... |
