DOI: 10.1109/lcomm.2017.2757941

Abstract: In this letter, we present a design method to find good protograph-based low-density parity-check codes with the numbers of nonzero elements in the parity-check matrix and decoding iterations both strictly limited. We utilize the protograph-based… read more here.

DOI: 10.1109/tcomm.2021.3077939

Abstract: In this paper, we propose a new method to design low-density parity-check Hadamard (LDPC-Hadamard) codes — a type of ultimate-Shannon-limit approaching channel codes. The technique is based on applying Hadamard constraints to the check nodes… read more here.

DOI: 10.1109/tcomm.2025.3615769

Abstract: In this paper, we propose a new class of globally-coupled low-density parity-check (GC-LDPC) codes, referred to as variable node (VN) based tail-biting (TB) GC-LDPC codes. Unlike conventional check node (CN) based GC-LDPC codes, which rely… read more here.

DOI: 10.1364/oe.25.003133

Abstract: In this paper, with the aid of mutual information and generalized mutual information (GMI) capacity analyses, it is shown that the geometrically shaped APSK that mimics an optimal Gaussian distribution with equiprobable signaling together with… read more here.
