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 ...

FPGA Implementation of a BPSK Modulator with Frequency Hopping. [PDF]
, 2021 PSK modulations are very widespread in communication due to their robustness to the noise. In order to avoid interference or for anti-jamming purposes, frequency hopping may be applied. In this work we present an FPGA implementation of a BPSK modulator based on frequency hopping.

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

Improved SNR estimation for BPSK and QPSK signals
Electronics Letters, 2009 A novel non-data-aided SNR estimation technique for BPSK and QPSK modulations in complex additive white Gaussian noise (AWGN) is proposed. It uses the constant amplitude property of in-phase and quadrature components of these modulations to achieve an improved performance.

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.
