High Throughput and Energy Efficient LDPC Decoders Using Multi-Split-Row Threshold Method

Low Density Parity Check (LDPC) codes have received significant attention due to their superior error correction performance, and have been considered by emerging communication standards such as 10 Gigabit Ethernet (10GBASE-T), Digital Video Broadcasting (DVBS2), WiMAX (802.16e), Wi-Fi (802.11n) and WPANs (802.15.3c). Due to the codes' inherently irregular and global communication patterns, high-speed systems that require many processing nodes typically suffer from large wire dominated circuits with low clock rates. The recently introduced split-row threshold decoding algorithms and architectures increase parallelism, significantly reduce wire interconnect complexity, and have a small increase in bit error rate compared to the standard MinSum decoding algorithm.
