简易m序列调制解调器前端设计

The Front End Design of a Simple m Sequence Modem

m序列是扩频通信方式的基础理论,应用较为广泛,m序列是对最长线性反馈移位寄存器序列的简称,可由带线性反馈的移位寄存器通过串行移位方式生成。文中通过对m序列生成的基本理论进行了详细介绍,并基于此设计了简易m序列调制解调器架构,和硬件描述语言代码,完成了仿真,测试。

Msequence is the basic theory of spread spectrum communication,which has been widely applied,m sequence is short for the longest of linear feedback shift register sequence,which can be generated by a serial shift register with a linear feedback shift register . In this paper,we introduced the basic theory of how to produce m - sequence in detail. Based on this,A simple m - sequence modem architecture was designed,together with the design using hardware described language code,and finished the simulated and tested.
