Abstract

Trellis coded modulation (TCM) schemes can be employed in conjunction with concatenated coding or automatic-repeat-request (ARQ) systems. The performance of such hybrid schemes operating in Rayleigh fading channels is addressed in the paper. The fading is assumed to be slow with respect to the symbol rate. New approximate error expressions are developed when a pilot tone is used to estimate the channel gain, and when the Viterbi decoding algorithm is modified such that side information can be generated to erase symbols or request retransmission
