基于信号仿真的通信信号环境构设方法研究

针对目前通信信号环境构设方法在便捷性、经济性方面的不足,提出采用信号仿真方法仿真通信信号的产生、发射、传播、接收、滤波和解调的全过程,并通过引入复数包络方法表示通信信号,减少数据处理量,在此基础上,划分了仿真功能模块、明确了模块间的输入输出数据,最后,给出了采用Simulink工具箱构设典型语音调频通信信号环境的实例,结果表明了所提方法的可行性和有效性。

The Construction Method of Communication EnvironmentBased on Signal Simulation

Aiming at the defects of convenience and economics to construction method of communication environment, the method of signal simulation is applied to simulate the signal generator, transmitter, signal transmission, receiver, filter and demodulator. The complex envelope is present to describe communication signal for decreasing the data. And the function module is established, the input data and output data between modules is confirmed. The last, the example of FM communication environment, which is established with Simulink, is built and analysised. The research result shows that the method of signal simulation is feasible and effective.
