摘　　要：随机码越来越受到人们的重视,被广泛应用于导弹、卫星、飞船轨道测量和跟踪、雷达、导航、移动通信、保密通信和通信系统性能的测量以及数字信息处理系统中。m序列是伪随机码中,带线性反馈移位寄存器的周期最长的一种基本序列。本文首先分析m序列的基本原理、结构、性质,然后实现了15位m序列的仿真以及硬件实现,最终用示波器观察波形。实验表明,使用该方法实现的m序列发生器,结构简单,速度快,适用范围广。Random yards increasing attention has been widely used for the guided missiles,satellites,and spacecraf t measurement and tracking,radar,navigation,mobile communications,secret communication and communication system performance measurement and digital information processing system.m sequence is pseudo-random code,with linear feedback shift register cycle has the longest basic sequence.This paper analyses the m,the basic principle of sequence structure,properties,and then realize 15 m sequence simulation and the hardware realization and finally with an oscilloscope observation waveform.Experiment shows that use the method of realization of m sequence generator,the structure is simple,fast,application scope.
