Full-length row-multiplier QC-LDPC codes with girth eight and short circulant sizes

J Wang, J Zhang, Q Zhou, L Zhang - IEEE Access, 2023 - ieeexplore.ieee.org
As a special case of a quasi-cyclic (QC) low-density parity-check (LDPC) code, a full-length
row-multiplier (FLRM) QC-LDPC code is described by a compact exponent matrix based on …
