We propose the "Multi-Split-Row" LDPC decoding method which allows further reductions in routing complexity, greater throughput, and smaller circuit area implementations compared to the previously proposed Split-Row decoding method. Multi-Split-Row is especially useful for regular high row weight LDPC codes. A 2048-bit full parallel decoder is implemented in a 0.18 µm CMOS technology using standard MinSum, Split-Row-2 and Split-Row-4 methods. The Split-Row-4 decoder delivers 7.1 Gbps throughput
more » ... with 15 decoding iterations, and has 3.2 times smaller circuit area and 5.2 times higher throughput than the standard MinSum decoder.
