This simulink program simulates the overall performance of Spread spectrum technique.

In a normal communication channel, it is often desirable to concentrate the information in as narrow a region of the frequency spectrum as possible in order to conserve available bandwidth and to reduce power. The basic spread spectrum technique, on

在matlab7.8版本上编译通过。 利用matlab的滤波器工具箱函数实现对直扩扩频通信过程的仿真模型，可以简单设定功率控制，多径传输，多值干扰等过程。-This program is compiled successfully in Matlab7.8 platform. With the matlab Filter Toolbox funtion to simulate the process of spread spectrum transmission. The simple
