Abstract :
An efficient multilevel coding system is constructed in this paper. Parallel decoding of levels (PDL) is adopted to guarantee short time delay. System performance with Ungerboeck partitioning (UP) and block partitioning (BP) is evaluated respectively and results show that with very short block component codes, such a MLC/PDL system can bring very good performance. For example, multilevel code (15,9,4)(15,11,3)(15,11,3) can obtain a coding gain up to 27dB compared with uncoded QPSK when BER is around 10-5
