... justifies the conclusions in [19–21], whi ch show that AF is not optimal in fading channels. According to the performance analysis for BPSK modulation in Rayleigh fading channels [32], the BER of the ... Furthermore, since the estimation quality of the first stage is available, we use BLUE to obtain ˆ θ for exploiting the quality information instead of using the MLE in the M...
