Abstract :
In this paper, a channel which is subject to multipath fading, by considering a doubly block fading model is presented. The performance of the channels with large coherence dimension and the receiver with the full knowledge of channel state information, which leads to a coherent fading model is studied. The calculations of the optimal values and the proof that QPSK is near optimal with the independent of the error-exponent constraint are proved.
