Abstract : —This paper deals with the recently introduced class of Non-Surjective Finite Alphabet Iterative Decoders (NS-FAIDs). First, optimization results for an extended class of regular NS-FAIDs are presented. They reveal different possible trade-offs between decoding performance and hardware implementation efficiency. To validate the promises of optimized NS-FAIDs in terms of hardware implementation benefits, we propose two high-throughput hardware architectures, integrating NS-FAIDs decoding kernels. Implementation results show that NS-FAIDs allow significant improvements in terms of both throughput and hardware resources consumption, as compared to a baseline Min-Sum decoder, with even better or only slightly degraded decoding performance.
