In this paper, we study an adaptive M-PSK modulation technique with a coherent detection over Rayleigh fading channels. The data rate is adapted according to the channel state. At the receiver, the fading is estimated using pilot symbols. To cancel the channel impact, we correct the received signal by dividing it by the estimated value of the fading. To adjust the modulation level, we propose a switching protocol which takes into account the channel estimation and prediction errors.
