直接扩频系统有噪声情况下的仿真分析

Because of spread spectrum communications anti-interference capability, hidden, and easy to implement in multi-site transmission, these advantages widely used in mobile communication, wireless data communications, and other areas. The direct sequence spread spectrum communication is the most typical use of spread spectrum methods of work. Communication technology is advancing rapidly, communications systems are becoming more complex, so in the design of communications systems research, before system hardware test, software simulation has become an indispensable part. In this paper, hardware design that lay the foundation for the purpose. We research directly spreading the performance of the system through system simulation. System View used as a simulation platform in the System Simulation ,we gets the system error characteristics.and compared with the theoretical values.
