Construction of Near-Optimum Burst Erasure Correcting Low-Density Parity-Check Codes
In this paper, a simple and effective tool for the design of low-density parity-check (LDPC) codes for iterative correction of bursts of erasures is presented. The design method co...

A Modified Bit-Flipping Decoding Algorithm for Low-Density Parity-Check Codes
― In this paper, a modified bit-flipping decoding algorithm for low-density parity-check (LDPC) codes is proposed. Both improvement in performance and reduction in decoding delay...

Error Exponents of Low-Density Parity-Check Codes on the Binary Erasure Channel
-- We introduce a thermodynamic (large deviation) formalism for computing error exponents in error-correcting codes. Within this framework, we apply the heuristic cavity method fro...

Investigation of Error Floors of Structured Low-Density Parity-Check Codes by Hardware Emulation
Abstract−Several high performance LDPC codes have paritycheck matrices composed of permutation submatrices. We design a parallel-serial architecture to map the decoder of any str...

Average Spectra and Minimum Distances of Low-Density Parity-Check Codes over Abelian Groups
Ensembles of regular low-density parity-check codes over any finite Abelian group G are studied. The nonzero entries of the parity matrix are randomly chosen, independently and uni...
