Low-density parity-check (LDPC) codes have attracted much attention over the past two decades since they can asymptotically approach the Shannon capacity in a variety of data transmission and storage scenarios. As a type of promising structured LDPC codes, the protograph LDPC codes not only inherit the advantage of conventional LDPC codes, i.e., excellent error performance, but also possess simple...
A doubly-generalized low-density parity-check (D-GLDPC) code is a low-density parity-check (LDPC) code, where both of the check nodes and variable nodes use linear block codes instead of repetition and single parity-check (SPC) codes. In this paper, we propose a class of D-GLDPC codes in which 3-dimensional (3-D) single parity-check product-codes (SPC-PCs) are used as super-check nodes (SCNs). We...
