Design And Implementation of an Efficient Wireless Channel Simulator

Aiming at the current high-efficiency and accurate simulation of wireless channel fading channels, the article adopts the simulation method of harmonic superposition, and designs a channel simulator by improving the incident angle and initial phase of the incoming wave. The test results show that the statistical distribution of the fading signal envelope and the Doppler power spectrum output by the channel simulator are consistent with the theoretical values. This method can be applied to real and fast reproduction of the propagation characteristics of wireless fading channels.
