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 ...

Cybersecurity Driven Quantum Digital Twin for Proactive Threat Reversal in Open RAN
IET Quantum Communication, Volume 7, Issue 1, January/December 2026.This paper presents a novel cybersecurity‐driven quantum digital twin (CQDT) architecture for proactive defence in 6G Open RAN. By integrating quantum observables and reinforcement learning, the framework maintains high fidelity and suppresses entropy under adversarial CPTP noise. CQDT achieves real‐time adaptation with sub‐20 ms latency, meeting URLLC

Superadditivity of Quantum Channel Coding Rate with Finite Blocklength Joint Measurements
, 2016 The maximum rate at which classical information can be reliably transmitted per use of a quantum channel strictly increases in general with $N$, the number of channel outputs that are detected jointly by the quantum joint-detection receiver (JDR).

Aperture jitter in BPSK systems
Electronics Letters, 2005 Aperture jitter effects in sampled systems have usually been modelled as additive noise, based on a sinusoidal input signal. However, in BPSK systems, large errors can occur if the jittered sample crosses a data bit boundary. This case is analysed here and found to be significant for cases of small jitter variance.

A Design Concept of CNN Counter to Noise Interference in Radar Signals Classification
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This article explains the relationship between the noise energy and the size of output feature maps, and advance the concept of compression and dilation of CNN architecture which depends on the balance of noise energy and the number of features. ABSTRACT Radar signals classification plays an increasingly significant role in electronic reconnaissance ...
