Security‐Enhanced Differential Binary‐Phase‐Shift‐Keying Quantum Key Distribution With a Wavelength‐Switchable Single‐Photon Carrier

Advanced Photonics Research, Volume 7, Issue 6, June 2026.
A single‐chip dual‐wavelength coherent photon source is proposed to add parametric uncertainty and improve the security of single‐photon differential binary‐phase‐shift‐keying quantum key distribution. This wavelength‐uncertain coding or decoying operation enables flexible and secure D‐BPSK‐QKD transmission over a wavelength‐division‐multiplexed ...

A Highly Efficient Two‐Sided Temporal Convolutional Neural Network for Wideband Digital Predistortion of RF Power Amplifiers

International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, Volume 39, Issue 3, May/June 2026.
ABSTRACT Behavioral models for Power Amplifier (PAs), particularly those based on Neural Networks (NNs), often suffer from high computational complexity when handling wideband signals. In this paper, we present a novel behavior model for wideband GaN PAs based on a Two‐Sided Temporal Convolutional Neural Network (TST‐CNN).

Contribution of non‐orthogonal multiple access signalling to practical multibeam satellite deployments

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 73-88, January/February 2026.
The potential gains of NOMA were evaluated in a satellite system with heterogeneous receivers, after considering the use of specific DVB‐S2X MODCODs, along with the impact of non‐linearities. It was concluded that a judicious power allocation in NOMA, jointly optimized with the IBO of the PAs, can yield significant sum‐rate gains.
