摘要
本文主要研究了卫星信道下直接序列扩频CDMA系统的抗干扰问题。在对系统抗干扰能力进行客观分析的基础上,指出可以从功率控制、窄带干扰抑制、多载波扩频等方面采取措施,以提高系统的抗干扰能力。
The paper studied the Anti-jamming question of direct sequence spread spectrum CDMA system in satellite channel. In order to enhance the Anti-jamming ability of CDMA system, sytem model and jamming signals were analized, then some meaures such as controlling power, controlling narrowhand jamming or multi-carrier spread spectrum were took and explain how to realize in the paper.
