主函数Alamouti(Nr,max_snr,max_err_symbol,symbol_per_fr a me)

　　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_fr a me)

　　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
