同频同调制信号的瑞利信道系统仿真设计
Simulation design of Rayleigh channel system for signals with same carrier frequency and modulation
摘要
Abstract
To eliminate the incompleteness of the communication simulation model,the Simulink of Matlab software is used to establish a receiver communication simulation model for signal transmission,receiving and separation. Taking the signals with same carrier frequency and modulation as the signal source of the model,the multipath Rayleigh fading channel is selected to simulate the actual working process of the receiver. The model includes signal source module,modem module,channel module, simulation receiving module,sampling filtering module and signal separation module. The influence of Rayleigh channel's path gain on signal blind separation was tested in the system. The simulation results show that the separation effect is relatively better with the increase of the channel gain and concentration of the signal. Therefore,the combination of the simulation system and hardware system prototype can provide the functional verification for testing signals and a reference for the operating environment of the actual receiver system.关键词
