The program simulates the BER of the main function twohop. m and some sub-functions at the receiver when the two-hop cooperative communication systems adopt AAF and DAF protocols respectively under different signal-to-noise ratios, assuming the Rayleigh channel. The transmission distance of S_RRDS_D is 1 m, the modulation mode is BPSK, the signal-to-noise ratio is -15 dB-15 dB, the receiver combination mode is ERC, and the number of iterations is 1000.
