Simulation of error trapping decoders on a fading channel

In this paper, we evaluate the performance of error trapping decoding when used to protect data over a mobile radio channel. The channel is represented by the Gilbert-Elliott (GE) model, with its parameters related to the physical quantities determining the fading statistics. Simulations are used to evaluate codeword and bit error probabilities for three different error correcting codes (linear block codes) for a number of scenarios. Using simplifying assumptions, analytical expressions are derived for the codeword error probabilities and these are shown to be in excellent agreement with simulation results
