直接序列扩频系统误码性能分析

Analysis of Bit Error Performance on Direct Sequence Spread Spectrum System

基于直接序列扩频通信系统原理,对系统在受到均匀连续频谱干扰、部分频带干扰、脉冲干扰时的误码性能进行了分析,并用Matlab进行了仿真.理论分析与仿真结果表明,在其他条件不变的情况下,减小干扰信号带宽,可提高系统误码率.

Based on the principles of the direct sequence spread spectrum communication system, the bit error performance of the system under the broad band jamming, partial band jamming and pulse jamming was analyzed and simulated by using Matlab software. The theoretical analysis and the simulation results show that decreasing the band of the jamming can result in improving the error rate of the system, in terms of other conditions being kept unchanging.
