扩频系统中伪随机码发生器的实现

Realization of Concrete Pseudo-Random Code Generator in Spread Spectrum Systems

由于m序列容易产生、规律性强、有许多优良的性能,在扩频通信中最早获得广泛的应用。介绍扩频通信系统的理论依据,接着引出m序列的原理,给出了DSP和MatLab在扩频系统中伪随机码发生器实现的方法,并给出了具体实现的源程序,具有一定的实用价值。

Since the m array has a lot of good functions such as generate easily and strong regularity, so it is one pioneer which is widely used in spread spectrum communications. Introduces the principle of spread spectrum system firstly, then to fetch out the principle of m array, gives two methods which can generate Pseudo-random code by DSP and MatLab, and at taches the source code, which has certain practical value.
