Abstract :
An adaptive forward error control and modulation scheme is proposed for slow Rayleigh fading channels. The adaptive scheme employs a family of RS codes of different rates and multiple phase shift keying (MPSK) modulation schemes according to the states of the channel. This uses a channel estimator to select the most appropriate codulation (coded-modulation) scheme. Simulation results show that the adaptive scheme gives significant improvement in the BER and throughput performance.
