Description: M=4的PSK通信系统进行蒙特卡罗仿真
仿真BPSK和4PSK调制信号在高斯信道下的性能，并与理论分析结果相比。
(1) 画出两条性能曲线，一条是根据理论平均错误概率画出，另一条是仿真曲线；
(2) 程序的基本流程：信源产生信息比特、调制、将调制信号送入信道(产生高斯白噪声的程序)、接收端检测、将检测结果与信源原始信息比较计算误符号率和误比特率；
(3) 在给定信噪比下，第二步需多次重复，以得到一个平均错误概率；
(4) 信噪比范围：BPSK(0dB – 10dB)，4PSK(0dB-14dB)，间隔是1dB 也可在BER=10-6左右终止。
(5) 信噪比计算 SNR=10log(Es/N0)=10log(REb/N0).
