基于Systemview的扩频通信仿真与分析

Simulation and analysis of spread spectrum communication based on the software Systemview

文章利用Systemview软件作为平台,对扩频通信中最典型的扩频工作方式———直接序列扩频系统(DSSS)进行了仿真分析;结果表明直扩系统的抗干扰能力远远大于普通的二进制系统,并且随着扩频增益的增大,系统的误码率越小;同时扩频系统性能的好坏很大程度上还取决于扩频码的特性。

Based on the software Systemview, direct sequence spread spectrum（DSSS） communication is simulated and analyzed. The simulation result shows that the anti-jamming capability of the DSSS communication system is better than that of common binary digital systems, that with the increasing of the spread spectrum（SS） gain, the probability of error bits decreases, and that the system＇s capability depends greatly on the characteristic of spread spectral sequences.
