Design of rate-compatible low-density parity-check codes for type-II hybrid ARQ systems
Tongxin xuebao, 2006 The design of powerful rate-compatible low-density parity-check codes（RC-LDPC）was constructed in zigzag structure for type-II hybrid ARQ systems.The generalized PEG algorithm was used in the process of constructing RC-LDPC codes to improve the ...

IET Communications, Volume 20, Issue 1, January/December 2026.This paper presents a two‐stage genetic algorithm based waveform design framework for OFDM integrated sensing and communication (ISAC) systems. In Stage‐1, a multi‐objective genetic algorithm jointly optimizes the peak‐to‐average power ratio (PAPR) and peak sidelobe level ratio (PSLR) under forward error correction and reserved subcarrier constraints ...

COMPARATIVE ANALYSIS OF LDPC AND BCH CODES ERROR-CORRECTING CAPABILITIES
Information and Telecommunication Sciences, 2014 The error-correcting capabilities of regular LDPC (Low Density Parity Check) codes and BCH (Bose-Chaudhuri-Hocquenguem) codes are examined. The qualitative analysis and the quantitative assessment of error-correcting abilities are performed for LDPC ...

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 ...

Hybrid VLC–IR Communication System With Beam‐Steered Uplink and Turbo Coding Under Mobility
IET Optoelectronics, Volume 20, Issue 1, January/December 2026.This paper presents a hybrid VLC–IR communication system integrating a beam‐steered infrared uplink with Turbo coding for reliable indoor optical wireless links. The proposed architecture achieves BER below 10−3 at 10 dB SNR and maintains stable coverage under NLOS conditions through adaptive beam steering.
