Adaptive error coding using channel prediction

In this paper, we construct a finite-state Markov chain model for a Rayleig h fading channel by partitioning the range of the received signal envelope into K intervals. Using a simulation of the classic two-ray Rayleigh fading model, a Markov transition probability matrix is obtained. Using this matr ix to predict the channel state, we introduce an adaptive forward error cor rection (FEC) coding scheme. Simulation results are presented to show that the adaptive FEC coding scheme significantly improves the performance of a wireless communication system.
