IET Communications, Volume 20, Issue 1, January/December 2026.This research proposes a Regularised Hyperparameter Bilevel Optimisation with Continual Learning‐based Deep Neural Network (RHBO‐CLDNN) for beamforming in an Ultra‐Wide Band (UWB) system. The RHBO ensures the hyperparameter efficiency at both upper and lower levels, which allows DNN to fine‐tune the unique characteristics of the UWB system, which leads

, 2018 Cell-free massive multiple-input multiple-output (MIMO) is a system comprising a very large number of access points (hundreds or thousands of access points) and a relatively smaller number of active users (tens or hundreds of users) distributed over a large area. The access points use directly measured channel characteristics to jointly serve all users

Multi-Cell Massive MIMO in LoS
, 2018 We consider a multi-cell Massive MIMO system in a line-of-sight (LoS) propagation environment, for which each user is served by one base station, with no cooperation among the base stations.

Metasurface Effect on the Performance of Planar Antennas for Wireless Communications
Radio Science, Volume 60, Issue 11, November 2025.Abstract This paper demonstrates the performance enhancement of a conventional planar antenna by incorporating metasurface (MTS) layer using a proposed unit‐cell array. The impact of MTS unit‐cell density on bit‐error‐rate (BER) and channel capacity (CC) in a point‐to‐point microwave link is investigated.
