Abstract
In this paper some nonstandard partitioning rules for 16QAM constellation are proposed. With these nonstandard partitioning rules a new MSD structure is generated. For the fixed component codes length the new structure can greatly reduce the complexity of MLC(Multilevel codes) system. The time delay is just 1/2 of that with traditional partitioning rules. Simulation results show that the new partitioning rules and the new MSD structure do not create any performance loss. Furthermore for the fixed time delay the new MLC system is better than the traditional MLC system and the performance improvement is about 0.25 dB with BER equal to 10-5.
