Abstract :
The performance of an improved multilevel coding (MLC) system with intralevel interleaving and iterative multilevel decoding in Rayleigh fading channels is studied. BCH codes are selected as component codes and code rates are distributed according to “capacity rule”. The Ungerboeck partitioning scheme and 8ASK modulation are used. The simulation results indicate that interleaving technique and iterative decoding can improve the performance of MLC system greatly
