摘要
利用一个完整的动态系统设计、仿真和分析的可视化环境System View,构造直接序列扩频通信系统仿真模型,利用该模型仿真分析,得到从信源扩频、调制、加噪声、到解扩和滤波等各个环节的直接序列扩频通信系统的时域图及其相关的时域技术数据,为通信系统设计技术的研究提供支持。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。
With the simulation module utilized, the time domain chart, spectrum chart and technical data of time domain of direct sequence＇s spread spectrum communication system can be obtained from signal source＇s spread spectrum, modulation, adding noise, dispreading, and filtering, which supports the design of communication system. The simulation result shows that the antijamming capability of the DSSS communication system is better than that of common binary digital systems.
