High-Performance NB-LDPC Decoder With Reduction of Message Exchange.

This paper presents a novel algorithm based on trellis min-max for decoding non-binary low-density parity-check (NB-LDPC) codes. This decoder reduces the number of messages exchanged between check node and variable node processors, which decreases the storage resources and the wiring congestion and, thus, increases the throughput of the decoder. Our frame error rate performance simulations show th...
