IET Communications, Volume 20, Issue 1, January/December 2026.This paper investigates new radio spectrum coexistence mechanisms, leveraging the currently uninhabited 6 GHz bands and aiming for fair coexistence of Wi‐Fi 6 and 5G new radio unlicensed (NR‐U). A novel two‐stage channel contention mechanism is proposed to explore additional spectrum access opportunities which remain unrealized in the existing channel ...

Artificial Noise Aided Directional Modulation with Multilog Frequency Diverse Array
IET Communications, Volume 20, Issue 1, January/December 2026.The basic principle of the proposed AN‐DM‐MFDA system is to allocate AN to leakage sidelobes instead of uniformly transmitting on the two‐dimensional plane. Moreover, we theoretically derive the average bit error rates as well as the secrecy capacity between the legitimate receiver and eavesdropper in the developed system.

Max-min weighted downlink SINR with uplink SINR constraints for full-duplex MIMO systems [PDF]
, 2017 In this paper, we investigate a max-min weighted signal-to-interference-plus-noise-ratio (SINR) problem in a full-duplex multiuser multiple-input-multiple-output system, where a full-duplex-capable base station (BS) equipped with multiple antennas ...

Transformer‐Based Fusion for Joint Routing and Resource Allocation in the Internet of Things
IET Communications, Volume 20, Issue 1, January/December 2026.In this work, we investigate decentralized joint routing and resource allocation for high‐quality path establishment at the network layer of the Internet of Things (IoT). We propose a novel optimization framework based on Transformer‐based Deep Reinforcement Learning (DRL), which enables the fusion of observations and actions along communication paths.

Mobility Management for the Low‐Altitude Economy: Latency‐Aware Handover Design
IET Communications, Volume 20, Issue 1, January/December 2026.This paper develops a latency‐aware mobility‐management framework for aerial vehicles operating in hybrid terrestrial non‐terrestrial networks. We formulate a MILP for optimal AV AP association and propose a greedy handover policy using predicted coverage, rate and handover latency.

Adaptable Bandwidth for Harmonic Step-Frequency Radar
International Journal of Antennas and Propagation, 2015 A spectrum sensing technique is described which is used to enhance the performance of harmonic step-frequency radar in the presence of harmful radio frequency (RF) interference (RFI). This technique passively monitors the RF spectrum for subbands of high
