Abstract :
The iterative convergence of iteratively detected coded modulation schemes having different block lengths, decoding complexity and an unequal error protection capability is studied, when communicating over AWGN channels using 8PSK modulation. More specifically, the coded modulation schemes investigated include multilevel coding (MLC), trellis coded modulation (TCM), turbo trellis coded modulation (TTCM), bit-interleaved coded modulation (BICM) as well as bit-interleaved coded modulation employing iterative decoding (BICM-ID). A novel three dimensional EXIT chart was introduced for studying the iterative convergence behaviour of the multistage decoding (MSD) scheme used in MLC
