Effect of interleaving on a Gilbert channel

Many models based on Hidden Markov Models were developped to modelise errors burst in communication channels. In this paper, we employ the widely used Gilbert model to modelise error bursts and evaluate the effects of interleaving. We derive an expression for the transition matrix in the presence of an interleaver. Starting from an identified error model, it is possible to simulate easily the effects of any interleaving depth. This allows in a simply way the choice of an interleaving degree and an forward error correction (FEC) code.
