Design of LDPC Codes: A Survey and New Results
This survey paper provides fundamentals in the design of LDPC codes. To provide a target for the code designer, we first summarize the EXIT chart technique for determining (near-)optimal degree distributions for LDPC code ensembles. We also demonstrate the simplicity of representing codes by protographs and how this naturally leads to quasi-cyclic LDPC codes. The EXIT chart technique is then ex...
متن کاملDesign of VLSI Implementation-Oriented LDPC Codes
Recently, low-density parity-check (LDPC) codes have attracted much attention because of their excellent errorcorrecting performance and highly parallelizable decoding scheme. However, the effective VLSI implementation of an LDPC decoder remains a big challenge and is a crucial issue in determining how well we can exploit the benefits of the LDPC codes in the real applications. In this paper, f...
متن کاملA Survey of different decoding schemes for LDPC block codes
-Low-density Parity-check (LDPC) code a very promising near-optimal error correction code(ECC), is being widely considered in next generation industry standards. In this paper, two simple iterative low complexity algorithms for decoding LDPC codes have been explained. These algorithms are implemented using real additions only and also not dependent on power spectral density. The survey paper pr...
