I simulated the SPACE TIME BLOCK CODED system based on Alamouti scheme, where the modulation is BPSK. Now I am trying to extend that to QPSK and higher modulations. Since for SISO channels, BER curve for BPSK and QPSK is equal in AWGN and fla

QPSK在AWGN信道下仿真,主要描述的是其在高斯白噪声背景下的误码性能的仿真-APSK simulink in AWGN chanel

产生QPSK调制信号，在此基础上，增加AWGN噪声信号。(A qpsk modulate signal plus an awgn signal is generated)
