Secret Key Extraction Using Stable Channel Impulse Response in OFDM Wireless Networks
IET Communications, Volume 20, Issue 1, January/December 2026.The process of converting a complex impulse response (CIR) highest peak into a binary sequence is called ‘quantisation’. By quantising the CIR highest peaks, Alice and Bob will generate the secret key bit sequences KA and KB, respectively. The number of CIR highest peaks is infinite, and these highest peaks can be easily selected from the set of CIRs ...

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.

Low-rate coding using incremental redundancy for GLDPC codes [PDF]
, 2008 In this paper we propose a low-rate coding method, suited for application-layer forward error correction. Depending on channel conditions, the coding scheme we propose can switch from a fixed-rate LDPC code to various low-rate GLDPC codes.

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 ...

LDPC Codes in Communications and Broadcasting [PDF]
IEICE Transactions on Communications, 2007 SUMMARY Low-density parity-check (LDPC) codes are one of the most powerful error correcting codes and are attracting much attention these days. LDPC codes are promising for communications and broadcasting as well where the use of error correcting codes are essential.

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.

A Decoding Algorithm for LDPC Codes Over Erasure Channels with Sporadic Errors
, 2010 An efficient decoding algorithm for low-density parity-check (LDPC) codes on erasure channels with sporadic errors (i.e., binary error-and-erasure channels with error probability much smaller than the erasure probability) is proposed and its performance ...
