Implementation of Channel Simulator for Broadband Communication Satellite Systems

摘要：

　　Hardware implementation and simulation method of channel simulator of Ka-band communication satellite systems are investigated in this paper,Based on FPGA+DSP hardware,the developed simulator can exactly simulate various satellite channel impairments including phase noise,time delay,Doppler,Ricean and Rayleigh fading,rain fading,additive white noise,modulated interference signals,spurious performance,amplitude-frequency response,and group delay.Up until now,this new simulator is the most comprehensive channel simulator.Furthermore,the designs of the key simulation modules including group delay and phase noise are presented in this paper,and their simulation accuracy are also discussed.Finally,Measurement results show that the proposed simulator has achieved good performance.
