摘要
介绍了直接序列扩频通信的理论基础和模型,并通过MATLAB提供的Simulink仿真平台对直扩通信系统进行了仿真,在不同的条件下运行了仿真系统,研究了扩频增益、调制方式和不同扩频码对系统性能的影响。
The theory base and the model of the direct sequence spread spectrum communication technology are presented. The simulation model of the direct sequence spread spectrum communication system is built by using Simulink, which is provided by MATLAB. In addition, the simulation program is run on the basis of different simulation conditions. Moreover, the relationship between the spread spectrum gain, the module methods, the spread spectrum code and the communication system performance are also studied.
