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

open access: yesiMeta, 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 ...

LDPC Codes for 2D Arrays [PDF]

open access: yesIEEE Transactions on Information Theory, 2014
Binary codes over 2D arrays are very useful in data storage, where each array column represents a storage device or unit that may suffer failure. In this paper, we propose a new framework for probabilistic construction of codes on 2D arrays. Instead of a pure combinatorial erasure model used in traditional array codes, we propose a mixed combinatorial ...

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

open access: yesIET 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 ...

Constructing LDPC Codes with Any Desired Girth

open access: yesSensors, 2021
In wireless sensor networks, the reliability of communication can be greatly improved by applying low-density parity-check (LDPC) codes. Algorithms based on progressive-edge-growth (PEG) pattern and quasi-cyclic (QC) pattern are the mainstream approaches

Scene‐Driven Semantic Alignment for Generative Communication in Underwater Images

open access: yesIET Signal Processing, Volume 2026, Issue 1, 2026.
Underwater images serve as one of the most intuitive media for human perception of underwater environments. However, the limited bandwidth and susceptibility to noise in underwater acoustic (UWA) channels pose significant challenges for traditional image encoding and transmission methods, thereby hindering high‐quality image reconstruction.

Encoding of QC-LDPC Codes of Rank Deficient Parity Matrix

open access: yesJournal of Engineering, 2016
the encoding of long low density parity check (LDPC) codes presents a challenge compared to its decoding. The Quasi Cyclic (QC) LDPC codes offer the advantage for reducing the complexity for both encoding and decoding due to its QC structure.

Spatially-Coupled MacKay-Neal Codes and Hsu-Anastasopoulos Codes

open access: yes, 2011
Kudekar et al. recently proved that for transmission over the binary erasure channel (BEC), spatial coupling of LDPC codes increases the BP threshold of the coupled ensemble to the MAP threshold of the underlying LDPC codes.

Pilot‐Based Iterative Path Estimation and Maximum Ratio Combining (MRC)–Based Signal Detection of Orthogonal Time–Frequency Space (OTFS) Modulation for 6G in Fractional Doppler Channels

open access: yesJournal of Computer Networks and Communications, Volume 2026, Issue 1, 2026.
The sixth generation (6G) wireless networks are used to provide a large coverage, and also this generation needed to support different emerging applications in harsh areas with higher user equipment mobility. For the above case, a new modulation technique called orthogonal time–frequency space (OTFS) modulation has emerged as a promising technique to ...
