Combined trellis-coded modulation and blind turbo equalisation

Per-survivor processing (PSP)-based blind turbo equalization is combined with various coded modulation schemes, which employ combined modulation and channel coding techniques. The proposed method exploits the enhanced data protection offered by either trellis-coded modulation (TCM), bit-interleaved coded modulation (BICM) or turbo-TCM (TTCM) and exhibits good performance in terms of its output bit error rate (BER). Explicitly, a BER comparable to that of a trained turbo equaliser is attained at the cost of a modest complexity increase.
