Abstract

In this paper, two globally-coupled low-density parity check (GC-LDPC) code constructing methods are presented. The first is a Reed-Solomon-like GC-LDPC code that eases the design parameter searching in algebraic code constructions. The parameters such as the finite field, the associated prime factors, or the number of local codes can be more easily determined. The directly masking approach, the second proposed scheme, facilitates flexible structure designs of the parity check matrices. The two approaches can be regarded as generalizations of the original GC-LDPC codes. The design examples and the simulation results show the feasibility of the proposed techniques. In addition to code constructions, some applications and usage scenarios of GC-LDPC codes are addressed as well.
