Summary, in English

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.
