Abstract
A method and apparatus are provided for encoding and decoding a communication signal. Processes for encoding and decoding the communication signal use a first low density parity-check code (LDPC) construction and a second low density parity-check code construction that differs from the first low density parity-check code construction. Multilevel coding (MLC) is applied to protect each address bit of a signal point by an individual LDPC code. In one embodiment, the first level is coded with a progressive edge-growth LDPC code, the second level is coded with a Reed-Solomon LDPC code and the third level is left uncoded.
