Abstract:
A low-complexity iterative decoding scheme for channel-polarized multilevel coding is proposed, halving the number of soft-decision decoders based on factor graph representation. The proposed scheme improves >0.25-dB net coding gain compared to the conventional 20%-overhead concatenated BCH/KP4 codes for the same number of soft-decision decoders.
