干扰存在背景下MSK相干接收机输出误码率研究

由于非合作接收等因素的影响，相对于通信信号而言，干扰具有一定随机性。本文在研究干扰存在条件下MSK相干解调输出误码率时，将干扰建模成随机参量信号，并推导了针对MSK相干解调的干扰生效条件。讨论了合成矢量图法和数值计算法两种方法，并采用Matlab编程，实现了数值计算法，比较了不同模型下几种干扰样式的优劣。

Study on Error Probability of the Outputs of Coherent MSK Receivers in the Jamming Environment

Compared to communication signal,jamming is stochastic for the non-cooperative receiving of the communication receivers.In this paper,the jamming is modeled as a kind of parameter stochastic signal,and then the condition that makes jamming effective is researched.Two methods,the synthetic vectorgraph method and the numerical computing method,are discussed.Especially the later one,with the help of Matlab language,is achieved to compare the efficiency of several kind of jamming and proved to be useful.
