Abstract :
Orthogonal frequency division multiplexing (OFDM) is proposed as a convenient digital modulation scheme to transmit data encoded by means of turbo trellis coded modulation (TTCM). The resulting transmission system is described and the advantages of using OFDM to transmit TTCM encoded data are highlighted. The system is investigated by means of simulations in order to assess its performance over dispersive deterministic channels and over dispersive Rayleigh fading channels. As a benchmark, a system having a similar computational complexity, but employing classical trellis coded modulation (TCM) to encode the data is also investigated
