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.

Non‐RASopathy Genetic Syndromes Identified as the Molecular Cause of Disease in Patients Previously Diagnosed With Noonan Syndrome

American Journal of Medical Genetics Part A, Volume 200, Issue 3, Page 661-672, March 2026.
ABSTRACT Noonan Syndrome (NS) is a clinically and genetically heterogeneous condition characterized by typical facial dysmorphisms, short stature, congenital heart defects, and developmental delays. While variants in genes such as PTPN11, SOS1, and RAF1 account for most genetically confirmed cases, diagnosis is challenging due to phenotypic overlap ...

Performance Analysis of CA‐Polar Code for 5G‐IoT Low Power Wide Area Networks

Internet Technology Letters, Volume 9, Issue 2, March/April 2026.
ABSTRACT CRC‐Aided Polar (CA‐Polar) codes are the standardized channel coding scheme for control channels of 5G eMBB service class due to their capacity achieving performance. This work aims to assess the compatibility and scalability of CA‐Polar codes toward low power IoT applications coming under the domain of LPWAN.

Deterministic Constructions for Large Girth Protograph LDPC Codes

, 2013
The bit-error threshold of the standard ensemble of Low Density Parity Check (LDPC) codes is known to be close to capacity, if there is a non-zero fraction of degree-two bit nodes.

Fast bootstrap and reliable readout using hidden references for DNA data storage

iMeta, Volume 5, Issue 1, February 2026.
This study provides a bootstrap readout framework for DNA data storage based on multiple‐fold hidden references. We employ a multi‐stage alignment and error correction strategy, transforming the de novo readout into a resequencing‐like workflow. Correlation to the hidden watermark reference identifies low‐error‐rate reads, and bit‐wise consensus ...

Wave-like Decoding of Tail-biting Spatially Coupled LDPC Codes Through Iterative Demapping

, 2017
For finite coupling lengths, terminated spatially coupled low-density parity-check (SC-LDPC) codes show a non-negligible rate-loss. In this paper, we investigate if this rate loss can be mitigated by tail-biting SC-LDPC codes in conjunction with ...

Performance Analysis of the LDPC‐Coded Hybrid LQAM‐MPPM for UWOC Systems

IET Optoelectronics, Volume 20, Issue 1, January/December 2026.
The effectiveness of LDPC codes in improving the performance of hybrid modulations is discussed, with coded 128‐QAM‐(12, 2) MPPM offering ~6.5 and 5.8 dB code gains at a BER of in strong and moderate turbulence, respectively. These results demonstrate the promise of hybrid modulation with LDPC as a robust and efficient modulation scheme for UWOC ...

Multiplicatively Repeated Non-Binary LDPC Codes [PDF]

, 2011
We propose non-binary LDPC codes concatenated with multiplicative repetition codes. By multiplicatively repeating the (2,3)-regular non-binary LDPC mother code of rate 1/3, we construct rate-compatible codes of lower rates 1/6, 1/9, 1/12,... Surprisingly,

Concatenated LDPC-Polar Codes Decoding Through Belief Propagation

, 2017
Owing to their capacity-achieving performance and low encoding and decoding complexity, polar codes have drawn much research interests recently. Successive cancellation decoding (SCD) and belief propagation decoding (BPD) are two common approaches for ...
