An Energy‐Tiered Clustering‐Based Blind Detector for RIS‐RSM Systems

open access: yesIET Communications, Volume 20, Issue 1, January/December 2026.
This paper proposes an energy‐tiered structure initialization (ETSI) algorithm for blind detection in reconfigurable intelligent surface (RIS)‐assisted spatial modulation systems. By decomposing the modulation constellation into multiple energy tiers and leveraging structured prototype initialization with tier‐normalized refinement, ETSI effectively ...

Hyperparameter‐Free Maximum Versoria Criterion Based Channel‐State Acquisition for mmWave Hybrid MIMO With Hardware Impairments

open access: yesIET Communications, Volume 20, Issue 1, January/December 2026.
This paper addresses channel estimation in mmWave (millimetre wave) hybrid MIMO (multiple‐input multiple‐output) systems impaired by residual transceiver hardware nonidealities, modelled as additive non‐Gaussian noise via Bussgang decomposition. A hyperparameter‐free maximum Versoria criterion (MVC)‐based channel estimator is proposed, featuring a ...

Massive MIMO Communications

open access: yes, 2016
Every new network generation needs to make a leap in area data throughput, to manage the growing wireless data traffic. The Massive MIMO technologycan bring at least ten-fold improvements in area throughput by increasing the spec-tral efficiency (bit/s/Hz/cell), while using the same bandwidth and density of basestations as in current networks.

Massive MIMO User Location Based Pilot Allocation in Massive MIMO Systems

open access: yesInternational Journal of Innovative Technology and Exploring Engineering, 2020
Aiming at the problem of massive MIMO pilot contamination, a user location information based pilot allocation scheme is proposed. The proposed scheme sorts the users and assigns pilots in accordance to the polar angle of the user's location in the polar coordinate system with the base station of the cell as the pole.

Regularised Hyper Parameter Bi Level Optimisation With Continual Learning Based Deep Neural Network for Beamforming in Ultra‐Wide Band System

open access: yesIET 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
