摘要
介绍软扩频系统和里德-索罗门编码的基本原理,提出一种基于里德-索罗门码序列的软扩频系统,并且用Simulink仿真工具对该系统进行了建模。为了验证系统的抗干扰性能,对其进行了仿真分析,给出了这种软扩频系统和一般直扩频系统在单频干扰和宽带干扰下的误码率,仿真结果表明:这种基于里德-索罗门码序列的软扩频系统对单频信号干扰和宽带干扰有很好的抑制效果。
This paper introduces the basic principle of Tamed Spread Spectrum System and Reed Solomon（RS） code, presents a novel Tamed Spread Spectrum System based on the sequence of RS code, also creates a model using the tool of Simulink. In order to verify its performance of anti-jamming, simulation analysis is made. The BER of Tamed Spread Spectrum System and traditional Direct Spread Spectrum System under the condition of single tone jamming and bandwidth jamming are obtained. The results demonstrate that the Tamed Spread Spectrum System based on the sequence of RS code can restrain the jamming greatly.
