Scene‐Driven Semantic Alignment for Generative Communication in Underwater Images
IET 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.

Design of Non-Binary Quasi-Cyclic LDPC Codes by ACE Optimization
, 2013 An algorithm for constructing Tanner graphs of non-binary irregular quasi-cyclic LDPC codes is introduced. It employs a new method for selection of edge labels allowing control over the code's non-binary ACE spectrum and resulting in low error-floor. The

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.

Implementation of Decoders for LDPC Block Codes and LDPC Convolutional Codes Based on GPUs [PDF]
IEEE Transactions on Parallel and Distributed Systems, 2014 With the use of belief propagation (BP) decoding algorithm, low-density parity-check (LDPC) codes can achieve near-Shannon limit performance. In order to evaluate the error performance of LDPC codes, simulators running on CPUs are commonly used. However, the time taken to evaluate LDPC codes with very good error performance is excessive. In this paper,
