Weight Distribution for Non-binary Cluster LDPC Code Ensemble [PDF]
, 2013 In this paper, we derive the average weight distributions for the irregular non-binary cluster low-density parity-check (LDPC) code ensembles. Moreover, we give the exponential growth rate of the average weight distribution in the limit of large code ...

Double-Layer Low-Density Parity-Check Codes over Multiple-Input Multiple-Output Channels
International Journal of Antennas and Propagation, 2012 We introduce a double-layer code based on the combination of a low-density parity-check (LDPC) code with the multiple-input multiple-output (MIMO) system, where the decoding can be done in both inner-iteration and outer-iteration manners.

Analysis and Optimization of a General Linking Matrix for JSCC Scheme Based on Double LDPC Codes
Entropy, 2023 A key component of the joint source-channel coding (JSCC) scheme based on double low-density parity-check (D-LDPC) codes is the introduction of a linking matrix between the source LDPC code and channel LDPC code, by which the decoding information ...

Efficient Design of Read Voltages and LDPC Codes in NAND Flash Memory Using Density Evolution
IEEE Access, 2023 Low-density parity-check (LDPC) codes play an important role in the reliability enhancement of commercial NAND flash memory. Unfortunately, due to the requirement of the reading speed of NAND flash memory, the LDPC decoder will not obtain precise soft ...

Multiedge-type low-density parity-check codes for continuous-variable quantum key distribution [PDF]
Physical Review A, 2018 Continuous-variable quantum key distribution utilizes an ensemble of coherent states of light to distribute secret encryption keys between two parties. One of the challenges is thereby the requirement of capacity approaching error correcting codes in the

Design and Analysis of Time-Invariant SC-LDPC Convolutional Codes With Small Constraint Length
, 2017 In this paper, we deal with time-invariant spatially coupled low-density parity-check convolutional codes (SC-LDPC-CCs). Classic design approaches usually start from quasi-cyclic low-density parity-check (QC-LDPC) block codes and exploit suitable ...
