Abstract

This paper has analyzed the PN code acquisition performance effects of adaptive narrow-band interference suppression filters in spread-spectrum systems based on detailed theoretical derivation.And complied with the theory of filters

the arnplitude frequency responses and group delay responses of adaptive narrow-band interference suppression filters

as well as the simulated results

are presented.These theoretical and simulated results show that because of narrow-band interferences and part of spread-spectrum signal being rejected by the adaptive interference suppression filter in the same time

large side-lobes will be formed in the output of correlator and the performance of PN code acquisition will be seriously affected.
