说明： 本文阐述了扩展频谱通信技术的理论基础和实现方法，利用MATLAB 提供的可视化
工具Simulink 建立了扩频通信系统仿真模型，详细讲述了各模块的设计，并指出了仿真建模
中要注意的问题。在给定仿真条件下，运行了仿真程序，得到了预期的仿真结果。同时，利
用建立的仿真系统，研究了扩频增益与输出端信噪比的关系，结果表明，在相同误码率下，
增大扩频增益，可以提高系统输出端的信噪比，从而提高通信系统的抗干扰能力。 (This paper describes the theory of spread-spectrum communication technology and implementation methods based on the use of visualization tools provided by MATLAB Simulink to establish a spread spectrum communication system simulation model, described in detail the design of each module, and pointed out that the simulation modeling to note problem. In the given simulation conditions, running a simulation program to obtain the desired simulation results. Meanwhile, the use of the simulation system to study the spreading gain and the relationship between the output signal to noise ratio, results show that the same bit error rate, increased spreading gain can increase the system output signal to noise ratio, thereby enhancing communication system disturbance.)
