摘 要：
介绍了一种离散Walsh函数的新型构造方法,并用该方法可以得到常见的三种不同排列顺序的Walsh函数,并分析了这三种不同编号方法的Walsh函数之间的关系,然后给出了采用这种新方法设计的Walsh函数序列发生器的电路框图,最后用Matlab对其进行了软件仿真,结果表明,该方法十分简便,电路结构简单,成本低,应用在CDMA通信系统中能明显减少带宽,提高频带的利用率,实用性好。

摘 要：
This paper introduces a new generator of discrete Walsh function, with which we get three common Walsh codes with different orders, and then discusses their relationship. Then the circuit frame of the new Walsh functional sequence generator is designed and given. Finally, simulation of software is made by using Matlab language. The results show that the new method can simplify design and reduce cost. Discrete Walsh function can be used in the CDMA communication system to evidently decrease bandwidth, and improve using efficiency of channel band. In conclusion, the new generator of Walsh code has good practicality.
