产生一个3载波的wcdma信号源，用于做仿真时的输入信号，现在通信系统常用的信号(generate wcdma source)

This m-file simulates MPSK (BPSK,QPSK,8PSK)with theoretical and simulated results using Gray coding. Numerical examples of a satellite link design are shown using QPSK and/or 8PSK when the bit rate(Rb)is greater than the channel bandwidth Wc (Band-limited channel).
