In this paper, we propose a novel multilevel coding scheme that employs low-density parity-check convolutional (LDPCC) codes. A combined decoding/ demodulation scheme is also considered. Unlike previous work on multilevel coding, the proposed scheme employs a single code with some structure that allows it to benet from the use of multilevel mapping. The proposed scheme can be seen as a form of bit-interleaved coded-modulation (BICM) that employs multilevel mapping and iterative demodulation and a code with structure.
