本程序用于完成BPSK、qpsk、pi/4qpsk、Oqpsk、8PSK、16QAM、32QAM、64QAM和128QAM的调制仿真。并可任意扩展到MPSK和MQAM。程序分成四个部分，fir.m对基带码元序列进行脉冲成型，可选矩形脉冲，升余弦脉冲和平方根升余弦脉冲； modal.m 为主程序，完成岁各种信号的基带星座图映射、脉冲成型和调制；pi4qpsk.m 为pi/4qpsk信号的星座图映射程序；test1.m给出一个简单的频谱显示测试。,This procedure for the com

Minimum Shift Keying (MSK), uses two frequencies which are separated by 1/2T and phase discontinuity is avoided in symbol boundaries. Further, MSK transmission can also be visualized as a variant of offset-qpsk technique, where sinusoidals are used f
