Suboptimum Viterbi algorithm for trellis-coded QAM scheme in multipath Rayleigh fading channels

Abstract

A new suboptimum Viterbi algorithm for trellis-coded quadrature amplitude modulation based on the channel state information of the multipath Rayleigh fading channel is proposed. Simulation results show that the proposed algorithm has merits for applications that require low bit energy-to-noise ratio.
