Regular and Irregular Quasi-Cyclic LDPC Codes
Xueqin Jiang, Moon Ho Lee, Jia Hou · 2011
This paper presents methods to the construction of regular and irregular low-density parity-check (LDPC) codes based on Euclidean geometries. Codes constructed by these methods are quasi-cyclic. The degree distributions of proposed LDPC codes can be optimized by the curve fitting approach in the extrinsic information transfer (EXIT) charts. Simulation results show that these codes perform very well with the iterative decoding.
