m序列发生器的设计与实现

Design and Realize of m Sequence Generator

伪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13位m序列的硬件电路设计和MATLAB、FPGA及SystemView软件仿真等,最后分析测试结果并提出设计想法。

Pseudorandom code is more and more attractive than ever before. It is widely used in the orbit measuring and tracing of guided missile, satellite and airship. The performance measurement of system such as radar, common communication, secrecy communication and communication system is also used in the system of digital signal processing （DSP）. The m sequence is a kind of pseudorandom code and longest period sequence. It is generated by LFSR. Moreover, this paper first analyzes the basic principle and properties of m sequence. Later we carry out the hardware design circuits 13-level m sequence. Furthermore this paper depicts three softwares of simulation like MATLAB, FPGA and SystemView and so on.. Subsequently it gives out the relevant results of testing in the process of design based on the analyzing and designing.
