SimAlamouti(12,20,24)
参数说明：
1.max_err_symbol的取值直接影响了仿真的精度：取值越大，精度越高，误符号率曲线也更平滑；但需更长的仿真
时间
2.一般max_snr小于15dB，程序中snr为信号噪声功率比
3.本程序仿真时未考虑帧与帧之间，信道衰落系数的相关性，因此symbol_per_frame一定程度上表征了信道相关时
间的大小，即在symbol_per_frame个QPSK信号发送时间内，信道衰落系数是不变或缓变的，而在下一帧数据中，
信道衰落系数可以认为已变成另一值
4.本程序假定在接收端已通过信道估计获得信道衰落系数-ALAMOUTI performs Monte-Carlo simulation and estimates Bit Error Rate
(BER) of Alamouti Scheme [1] over Rayleigh channel. The scheme presumes
2 transmit (Tx) and arbitrary number of receive (Rx) elements.
If Rx=1 (one receive element) ALAMOUTI is transformed to the order 2
transmit diversity scheme with Maximum Ratio Combining (MRC). The
modulation format is MPSK with arbitrary order M which can be
controlled by user.
