Abstract

Turbo trellis-coded modulation (T-TCM) is one of several techniques for combining turbo codes with multilevel modulation in order to save the bandwidth of the transmission systems. T-TCM was shown to perform very well on AWGN channels, but its performance over frequency-selective fading channels is unknown. In this paper, a system model to investigate the performance of T-TCM schemes over frequency-selective fading channels is proposed. Simulation results show that when an appropriate receiver is available, T-TCM also performs well on frequency-selective fading channels. T-TCM performance is much better than any other coded-modulation scheme for this type of channel
