多进制正交码扩频系统的帧同步

Frame Synchronization in an M-ary Orthogonal Coded Spread Spectrum System

多进制正交码扩频系统能有效解决传输带宽与处理增益间的矛盾,保证通信有效、准确、迅速地进行。本文介绍了多进制正交码扩频和解扩原理,并基于m序列与Walsh序列的对应关系,给出了一种帧同步方法。

An mary orthogonal coded spread spectrum system can effectively settle the conflict between transmission bandwidth and transaction gain, thus ensuring an effective, accurate and rapid communication. This paper presents the principle of an mary orthogonal coded spread spectrum and despreading, and then puts forward a method for frame synchronization, based on the corresponding relationship between m sequence and Walsh sequence.
