Abstract
Based on different partitioning rules for MQAM constellations. Nonstandard MLC/MQAM schemes had been proposed to reduce the calculation of the individual capacity. In this paper, performance of the proposed MLC/MQAM schemes in well-defined OFDM systems are discussed with punctured convolutional codes as component codes. Compared with traditional MLC/MQAM and MQAM without MLC in OFDM systems, simulation results show that the nonstandard MLC/MQAM schemes can get better performance and lower complexity.
