Construction of Algebraic-Based Variable-Rate QC-LDPC Codes
2021 IEEE International Symposium on Information Theory (ISIT)(2021)
Abstract
In this paper, we concentrate on one algebraic-based quasi-cyclic low-density parity-check (QC-LDPC) code constructed from two subsets of a finite field and generalize it to propose a class of variable-rate QC-LDPC (VR-QC-LDPC) codes, whose parity-check matrices are nested horizontally and have constant number of rows. Thus the proposed codes are significant at least in terms of storage complexity...
