Abstract :
We construct a finite-state Markov chain model for a Rayleigh fading channel by partitioning the range of the received signal envelope into K intervals. From a simulation of the classic two-way Rayleigh fading model, a Markov transition probability matrix is obtained. Based on this matrix, we introduce an adaptive forward error correction (FEC) coding scheme. Simulation results show that the adaptive FEC coding scheme significantly improves the performance of a wireless communication system
