Abstract

According to the capacity rule, the performance of multilevel coding (MLC) schemes with 8ASK modulation and three set partitioning strategies over AWGN channels is investigated. Two different decoding methods, which are multistage decoding (MSD) and parallel decoding on level (PDL), are used. In each scheme BCH codes with code lengths of 127 are used as component codes. Numerical results indicate that MSD is a sub-optimal decoding method of MLC for AWGN channels. For Ungerboeck partitioning (UP) and mixed partitioning (MP), the MSD method is strongly recommended to use for the MLC system, while for block partitioning (BP), PDL is suggested to use as a simple decoding method compared with MSD.
