An LDPC codec chip supporting four code rates of IEEE 802.15.3c applications is presented. After utilizing row-based layered scheduling, the normalized min-sum (NMS) algorithm can reduce half of the iteration number while maintaining similar performance. According to the unique code structure of the parity-check matrix, a reconfigurable 8/16/32-input sorter(More)
