Analysis of Quasi-Cyclic LDPC codes under ML decoding over the erasure channel [PDF]
, 2010 In this paper, we show that Quasi-Cyclic LDPC codes can efficiently accommodate the hybrid iterative/ML decoding over the binary erasure channel. We demonstrate that the quasi-cyclic structure of the parity-check matrix can be advantageously used in ...

Multi-Code-Rate Correction Technique with IR-QC-LDPC: An application to QKD [PDF]
, 2018 In this paper, we report an encoding and decoding method for irregular-quasic-cyclic low-density parity-check (IR-QC-LDPC) codes with multi rates. The algorithm is applicable to parity-check matrices which have dual-diagonal parity structure. The decoding adopts normalized min-sum algorithm(NMSA).

Construction of Parallel RIO Codes using Coset Coding with Hamming Codes [PDF]
, 2017 Random input/output (RIO) code is a coding scheme that enables reading of one logical page using a single read threshold in multilevel flash memory. The construction of RIO codes is equivalent to the construction of WOM codes. Parallel RIO (P-RIO) code is an RIO code that encodes all pages in parallel.

An Efficient Construction Method for Quasi-Cyclic Low Density Parity Check Codes
IEEE Access, 2017 In this paper, we propose an optimized belief propagation (OBP) based progressive edge-growth (PEG) method for constructing quasi-cyclic low density parity check (QC-LDPC) codes. In this proposed method, Tanner graphs are built by progressively appending
