主函數(shù)Alamouti(Nr,max_snr,max_err_symbol,symbol_per_frame)
調(diào)用函數(shù)QpskMapping(psudo_bit_sequence)--二進(jìn)制數(shù)據(jù)到QPSK信號(hào)的變換
調(diào)用函數(shù)RayleighCH(Nr,Nt)--瑞利衰落信道模擬
仿真示例:
Alamouti(1,12,20,24)
說明:
1.2根發(fā)射天線、1根接收天線
2.最高信噪比為12dB,即仿真范圍為0dB到12dB
3.在每個(gè)信噪比條件下,誤符號(hào)數(shù)超過20即停止該信噪比條件下的仿真
4.每一幀數(shù)據(jù)為24個(gè)QPSK符號(hào)
綜合仿真函數(shù)SimAlamouti(max_snr,max_err_symbol,symbol_per_frame)
具有一根接收天線系統(tǒng)的SER性能與二根接收天線的系統(tǒng)SER性能比較
