基于DSP的直接序列扩频信号中窄带干扰的抑制算法及实现
0
()
摘要:
直扩系统的抗干扰能力由其处理增益决定,当其处理增益不足以对抗强干扰时,则需寻找其他干扰抑制来提高系统性能。本文研究了一种直扩信号的干扰抑制算法,对其工作原理进行了分析,给出了干扰复制和门限算法,并讨论了其中的非线性运算的DSP实现问题。

Algorithm and Realization for Narrow-Band Interference Suppression Based on DSP in DSSS Communications
()
Abstract:
A Direct Sequence Spread Spectrum(DSSS)system is well known for its inherent anti-jam character because of its processing gain.When the processing gain is not high enough to suppress the interference, some other effective methods must be found .This paper introduces an advanced way to suppress narrow band interference in DSSS signal, analyzes its principle, and illuminates the DSP implementation of nonlinear algorithm.
