摘　　要：本文就直接序列扩频系统中时域窄带干扰抑制滤波器的相位响应对PN码的捕获性能进行了深入的分析,并给出了窄带干扰抑制滤波器的群延迟响应等仿真结果,及PN码捕获的结果。理论分析和仿真结果表明滤波器的相位特性对于PN码的捕获性能会产生严重的影响。This paper has analyzed the PN code acquisition performance effects of group delay response of narrow band interference suppression filters in DS-SS, the simulated results of the group delay responses of the narrow-band interference suppression filters are presented, and results of acquisition are presented too. These theoretical and simulated results show that because of the non-linear phase response the performance of PN code acquisition is seriously affected.
