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.

Split-extended LDPC codes for coded cooperation [PDF]
2010 International Symposium On Information Theory & Its Applications, 2010 We propose a new code design that aims to distribute an LDPC code over a relay channel. It is based on a split-and-extend approach, which allows the relay to split the set of bits connected to some parity-check of the LDPC code into two or several subsets. Subsequently, the sums of bits within each subset are used in a repeat-accumulate manner in order

Adaptive Offset Min‐Sum Decoder for 5G‐NR BG2 LDPC Codes Using Genetic Algorithm
Applied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.This paper proposes a more efficient resource‐constrained decoding algorithm for Adaptive Offset Min‐Sum (A‐OMS) low‐density parity check (LDPC) optimized decoder parameters in fifth‐generation New Radio (5G‐NR) Base Graph 2 codes (BG2). To curb the challenge of observing the all‐time finest offset to use the irregular BG2 structure, a genetic ...

Journal 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 ...

Comparing GFDM With OFDM for Use in 6G Communication From a New Perspective
Journal of Electrical and Computer Engineering, Volume 2026, Issue 1, 2026.The most important challenges facing 6G communication systems are the large amount of data and low latency as compared to previous generations. Therefore, it has become necessary to use advanced technologies to meet the requirements of 6G wireless communication systems.

Efficient Helicopter-Satellite Communication Scheme Based on Check-Hybrid LDPC Coding
Tsinghua Science and Technology, 2018 When implementing helicopter-satellite communications, periodical interruption of the received signal is a challenging problem because the communication antenna is intermittently blocked by the rotating blades of the helicopter.

Tanner (3, 23)-Regular QC-LDPC Codes: Cycle Structure and Girth Distribution
IEEE AccessThis paper studies a class of quasi-cyclic LDPC (QC-LDPC) codes, i.e., Tanner (3, 23)-regular QC-LDPC codes of code length $23p$ with $p$ being a prime and $p \equiv 1 (\mathrm {mod} 69)$ .
