Using MATLAB programming for PSK and DPSK modulation and demodulation process are simulated, and generate two systems under AWGN channel bit error rate curve, requirements:
(1) through berawgn function in MATLAB to get the theoretical value of the bit error rate curve, to get the bit error rate of the simulation value compared with the theoretical value, observe whether the match, and analyze the reason,
(2) are binary, quaternary DPSK and PSK system under AWGN channel bit error rate curve of the theoretical value and simulation value,
