Low-Density Parity-Check Codes: Research Status and Development Direction

In this paper, we conclude five kinds of methods for construction the regular low-density parity matrix H and three irregular parity-check H. Through analysis code rate parameters these eight structures, find that tends to be more flexible parameter variability is enhanced. We propose current development cost should lower with progress electronic technology need research on practical Low-Density Parity-Check Codes (LDPC). Combined application quantum distribution key, urgently explore direction relevant theories technologies LDPC codes in other fields information future.
