摘　　要：伪随机m序列具有许多优良的特性,尤其是自相关特性使它变成精确测距定距系统中经常采用的一种伪随机序列。本文首先搭建扩普通信中最常用的伪随机m序列的Simulink调相原理框图,然后按照框图建立伪码调相系统的仿真模型并介绍各个模块参数的设置方法。基于实现简单,距离截止特性好,抗干扰能力强等优点,伪码调相系统的研究有着较高的应用价值和深刻的研究意义。The pseudo--random m sequence has many fine characteristics, the autocorrelation charac- teristic causes it to turn the precise range finder in particular surely to be apart from one kind of pseudo-- random sequence which in the system uses frequently.This article first builds most commonly used pseudo --random m sequence Simulink phase modulation functional block diagram, then introduces each module parameter according to the pseudo--code phase modulation system simulation model . Based on simple, good cut--off characteristic , strong antijamming ability and so on the merits, the pseudo--code phase modulation system design and the realization have the high application value and the profound research sig- nificance.
