【Abstract】 Mathematical models of AWGN channel and multipath Rayleigh fading channel is established and simulated by the MATLAB software.Taking the BFSK signal as an example,a stimulation analysis of the performance of this signal in the two channels is made.The result showed that the BER of signal in AWGN is lower than in multipath Rayleigh fading channel in the condition of the same SNR.更多还原
