Adaptive Coding‐Based Quantum Communication System for Image Transmission
Electronics Letters, Volume 61, Issue 1, January/December 2025.Adaptive coding‐based quantum communication demonstrates the superior robustness and higher image quality compared to the adaptive coding‐based classical communication in varying channel noise conditions and bandwidth‐restricted applications. ABSTRACT This work presents a quantum communication system enhanced with adaptive coding, aimed at improving ...

Doped low-density parity-check codes
Digital Communications and NetworksIn this paper, we propose a doping approach to lower the error floor of Low-Density Parity-Check (LDPC) codes. The doping component is a short block code in which the information bits are selected from the coded bits of the dominant trapping sets of the ...

Comparison of Polar Decoders with Existing Low-Density Parity-Check and Turbo Decoders
, 2017 Polar codes are a recently proposed family of provably capacity-achieving error-correction codes that received a lot of attention. While their theoretical properties render them interesting, their practicality compared to other types of codes has not ...

A Non‐Binary Dual Cascade Polar Codes Construction and Low‐Complexity SCL Decoding
Electronics Letters, Volume 61, Issue 1, January/December 2025.First, we design an error‐correction approach including two cascade non‐binary polar coding (NB‐CPolar) structures and a cyclic redundancy check (CRC) code. Second, we propose a low‐complexity decoding algorithm based on non‐binary successive cancellation list (NB‐LSCL) decoding.

CeSR + Assisted LDPC: A Holistic Strategy to Improve MLC NAND Flash Reliability
IEEE Access, 2020 NAND flash suffers from program interference and retention errors, which negatively affect its reliability. Existing schemes preprocess raw data before writing them to reduce Raw Bit Error Rate (RBER) and leverage ECCs (such as LDPC codes) to reduce ...

On the Invisible Backdoor Attacks on Peer‐to‐Peer Semantic Vehicular Networks
Electronics Letters, Volume 61, Issue 1, January/December 2025.ABSTRACT Peer‐to‐peer semantic vehicular networks (P2P‐SVNs) use semantic communication to enable efficient vehicle‐to‐vehicle interaction by exchanging meaning instead of raw data. However, P2P‐SVNs face unique backdoor threats where attackers embed triggers in semantic features. Current research predominantly focuses on explicit trigger patterns that

A High Throughput Implementation of QC-LDPC Codes for 5G NR
IEEE Access, 2019 Quasi-cyclic low-density parity-check (QC-LDPC) codes are the choice for data channels in the fifth generation (5G) new radio (NR). At the transmitter side, code bits from the QC-LDPC encoder are delivered to the rate matcher.

Optimum Linear LLR Calculation for Iterative Decoding on Fading Channels
, 2007 On a fading channel with no channel state information at the receiver, calculating true log-likelihood ratios (LLR) is complicated. Existing work assume that the power of the additive noise is known and use the expected value of the fading gain in a ...
