Puncturing is a good way to achieve Rate-Compatible (RC) family codes with high rate. In this paper, asimple yet efficient puncturing strategy for Low Density ParityCheck (LDPC) codes with diagonal structure is proposed andanalyzed. In order to minimize the recovery step of puncturednodes, all the parity nodes (PNs) are assumed being punctured atfirst and then recovered step by step. The algorithm...
In this paper, we propose a new improved algorithm to reduce the decoding complexity of NB-LDPC codes especially when the number of iteration is large. The proposed algorithm is based on the extended min-sum (EMS) which truncates the message vectors and trellis-based EMS (T-EMS) which employs the trellis representation. Our modification of EMS introduces the thresholds to further truncate the incoming...
