A Massive Grant‐Free Random Access Scheme Based on Spectrum Sensing and Preamble Delay

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper introduces cognitive radio (CR) and preamble delay (PD) to reduce access collisions, together with non‐orthogonal multiple access (NOMA) to improve spectrum efficiency, and thus proposes an efficient CR‐NOMA‐PD‐based massive grant‐free random multiple access scheme.

Communication‐Security Co‐Design for Federated Learning in Grant‐Free NOMA IoT Networks

IET Communications, Volume 20, Issue 1, January/December 2026.
This article presents SA‐PPO, a Security‐Aware Proximal Policy Optimisation framework for federated learning over grant‐free NOMA (non‐orthogonal multiple access) in IoT networks. By jointly optimising access control, resource allocation, and trust‐weighted aggregation using cross‐layer indicators, SA‐PPO enhances both communication reliability and ...

Digital Self‐Interference Cancelation Method Based on Multi‐Domain Jamming Frequency‐Shift Fingerprint Design

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
To address the issue of self‐interference cancelation in simultaneous transmission and reception jammer where self‐interference and signal‐of‐interest are correlated, this paper proposes a novel digital self‐interference cancelation method based on frequency—shift fingerprint design from a perspective of signal characteristics.
