Description: 主函数Alamouti(Nr,max_snr,max_err_symbol,symbol_per_frame)
调用函数QpskMapping(psudo_bit_sequence)－－二进制数据到QPSK信号的变换
调用函数RayleighCH(Nr,Nt)－－瑞利衰落信道模拟
仿真示例：
Alamouti(1,12,20,24)
说明：
1.2根发射天线、1根接收天线
2.最高信噪比为12dB，即仿真范围为0dB到12dB
3.在每个信噪比条件下,误符号数超过20即停止该信噪比条件下的仿真
4.每一帧数据为24个QPSK符号
综合仿真函数SimAlamouti(max_snr,max_err_symbol,symbol_per_frame)
具有一根接收天线系统的SER性能与二根接收天线的系统SER性能比较
