Non-binary LDPC codes
-
Non-binary low-density parity-check (NBLDPC) codes have a better error-correcting performance in comparison with their binary counterparts when the code length is moderate. However, NB-LDPC decoding is high complexity, especially the check node processing. In this paper, a novel check node processing algorithm and corresponding architectures are proposed for the trellis min-max NB-LDPC decoding to reduce the hardware complexity. A layered decoder architecture is implemented for the (2304, 2048) NB-LDPC code over GF(16) based on the proposed algorithm with a 90-nm CMOS technology.

The implementation results showed that the OMO-BS-TMM algorithm achieves the almost similar error-correcting performance, and a reduction of the complexity by 31.8% and 20.5% for the whole decoder, compared to previous works. Moreover, the proposed decoder achieves a higher throughput at 1.4 Gbps, compared with the other state-of-the-art NBLDPC decoders.
