这个程序是用来解调OQPSK的，改一下就可以解MPSK，QAM和QPR没试过，理论上可以。

Sound modulator: an implementation of sound modulation algorithms like: AM, QAM, PM and FM.

用MATLAB实现功能，根据索引值进行复数调制，可选调制方式有BPSK、QPSK、16QAM、64QAM-MATLAB function, according to the index values for complex modulation, can XuanDiao means has BPSK, QPSK, 16 qam, 64 qam
