MATLAB在通信系统仿真中的应用

he theory base and realizing methods of the spread spectrum communication technology was presented in this study. The simulation model of the spread spectrum communication system was built by using SIMULINK, which is provided by MATLAB.In addition, each module of the simulation model was introduced in detail, and pointed out the problems that must be pay attention to in the system simulation. On the basis of the designed simulation conditions, the simulation program was run and the anticipant results were gained. Moreover, the relationship between the spread spectrum gain and the fan-out error rate was also studied by use of the simulation system. The results showed that on the base of the same error rate, if the spread spectrum gain was enlarged, the Signal—to—Noise of the system fan—out would be enhanced and the anti—jamming capability of the cominunicarlon system would also be enhanced.
