说明：  Simulink的通信模块库中以“M-PSK”调制、解调模块实现了一般M元相位调制解调模型。以“M-DPSK”调制、解调模块实现了一般M元差分相位键控模型。为了建模方便，还直接提供了BPSK、DBPSK、QPSK、DQPSK等等调制解调模型。
(The general M-ary phase modulation and demodulation model is implemented in Simulink's communication module library with "M-PSK" modulation and demodulation module. A general M-ary differential phase keying model is implemented with the "M-DPSK" modulation and demodulation module. For the convenience of modeling, the modulation and demodulation models of BPSK, DBPSK, QPSK, DQPSK, etc. are also directly provided.)
