摘　　要：System View是由美国ELANIX公司推出的、基于Windows环境下的可视化软件工具,主要用于信号级的系统仿真,是电路与通信系统设计、仿真时强有力的动态系统分析工具。利用System View动态分析仿真平台搭建了地域通信网的QPSK通信系统模型,并通过仿真给出高斯、单音、噪声调频、BPSK和QPSK五种干扰信号在该系统中的干扰效果和误码率。通过用System View对QPSK系统的仿真,可以看出单音和噪声调频是对QPSK通信系统最有效的干扰样式。System View is a visualization software tool based on Windows produced by American ELANIX, mainly used for system simulation, signal level, design, circuit simulation and communication system dynamic system powerful analysis tool. Based on System View dynamic analysis simulation platform,a QPSK communication system model of communication network is built . The simulation results of Gauss, BPSK, tone, noise FM and QPSK five kinds of interference signal interference effect in the system and the bit error rate are given. By using System View simulation of the QPSK system, tone and FM noise is the most ef- fective jamming of QPSK communication system.
