Multi-level coding/modulation using LDPC convolutional codes
Författare
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.
