Abstract:

The recently proposed Split-Row decoding algorithm provides signicant improvements in the throughput, hardware efciency and energy efciency when compared to existing soft decision decoding algorithms at the cost of some error performance loss. In this paper we propose Split-Row Threshold which outperforms the Split-Row algorithm while maintaining the same level of complexity. Simulation results show that the algorithm provides 0.2 dB coding gain over Split- Row decoding and is within 0.15-0.2 dB of SPA and MinSum normalized.
