IEEE Access, 2016 Channel codes, such as low-density parity-check (LDPC) codes, may be employed in wireless communication schemes for correcting transmission errors. This tolerance to channel-induced transmission errors allows the communication schemes to achieve higher ...

Entropy, 2023 In this article, a graph-theoretic method (taking advantage of constraints among sets associated with the corresponding parity-check matrices) is applied for the construction of a double low-density parity-check (D-LDPC) code (also known as LDPC code ...

Comparison of LDPC block and LDPC convolutional codes based on their decoding latency
2012 7th International Symposium on Turbo Codes and Iterative Information Processing (ISTC), 2012 We compare LDPC block and LDPC convolutional codes with respect to their decoding performance under low decoding latencies. Protograph based regular LDPC codes are considered with rather small lifting factors. LDPC block and convolutional codes are decoded using belief propagation.

Design of LDPC Codes: A Survey and New Results
, 2006 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.

Construction of Quantum LDPC Codes From Classical Row-Circulant QC-LDPCs [PDF]
IEEE Communications Letters, 2016 Classical row-circulant quasi-cyclic (QC) low-density parity check (LDPC) matrices are known to generate efficient high-rate short and moderate-length QC-LDPC codes, while the comparable random structures exhibit numerous short cycles of length-4. Therefore, we conceive a general formalism for constructing nondual-containing Calderbank–Shor–Steane (CSS)

Learning Quantization in LDPC Decoders
2022 IEEE Globecom Workshops (GC Wkshps), 2022 Finding optimal message quantization is a key requirement for low complexity belief propagation (BP) decoding. To this end, we propose a floating-point surrogate model that imitates quantization effects as additions of uniform noise, whose amplitudes are trainable variables.

Algebra-Assisted Construction of Quasi-Cyclic LDPC Codes for 5G New Radio
IEEE Access, 2018 Quasi-cyclic LDPC (QC-LDPC) codes have been accepted as the standard codes of 5G enhanced mobile broadband data channel. These standard codes are designed to support multiple lifting sizes and possess rate-compatible property, which can help adapt ...

Simplified variable-scaled min sum LDPC decoder for irregular LDPC codes [PDF]
2014 IEEE 11th Consumer Communications and Networking Conference (CCNC), 2014 Min-Sum decoding is widely used for decoding LDPC codes in many modern digital video broadcasting decoding due to its relative low complexity and robustness against quantization error. However, the suboptimal performance of the Min-Sum affects the integrated performance of wireless receivers.

Construction of regular quasi-cyclic protograph LDPC codes based on Vandermonde matrices
, 2008 In this contribution, we investigate the attainable performance of quasi-cyclic (QC) protograph Low-Density Parity-Check (LDPC) codes for transmission over both Additive White Gaussian Noise (AWGN) and uncorrelated Rayleigh channels.
