Collaborative Beamforming for Multi‐Target Localization Using Passive Anchors

Electronics Letters, Volume 62, Issue 1, January/December 2026.
A joint collaborative beamforming strategy for passive sensor network is proposed active sensors generate collaborative beam to power up the passive sensors and attain accurate self‐localization. ABSTRACT Using wireless passive sensor nodes as anchors is a cost‐effective way for localization system.

Gaussian Channel Model for Mobile Multipath Environment

EURASIP Journal on Advances in Signal Processing, 2004
A model of an angle-spread source is described, termed the “Gaussian channel model” (GCM). This model is used to represent signals transmitted between a user equipment and a cellular base station.

A 3D Non‐Stationary Wideband GBSM for Low‐Altitude UAV Channels in Rail Environments

IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.
This paper presents a three‐dimensional (3D) wideband non‐stationary Geometry‐Based Stochastic Channel Model (GBSM) for low‐altitude unmanned aerial vehicle (UAV) communications. Distinct from existing modelling frameworks, the proposed model integrates air‐to‐air (A2A) and air‐to ground (A2G) scenarios into a generalised channel model. Moreover, a two‐

Localization using Angle-of-Arrival (AoA) Triangulation

Proceedings of the International Workshop on Environmental Sensing Systems for Smart Cities
Indoor localization is a long-standing challenge in mobile computing, with significant implications for enabling location-aware and intelligent applications within smart environments such as homes, offices, and retail spaces. As AI assistants such as Amazon Alexa and Google Nest become increasingly pervasive, microphone-equipped devices are emerging as

Joint received signal strength, angle-of-arrival, and time-of-flight positioning [PDF]

, 2019
This paper presents a software positioning framework that is able to jointly use measured values of three parameters: the received signal strength, the angle-of-arrival, and the time-of-flight of the wireless signals.

Joint Time Synchronisation and Localisation Method by TDOA Observation in 5G Networks

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This work proposes a method for joint time synchronisation and localisation problems and proposes to obtain the initial values of the alternating iteration algorithm through solving the MVIE problem. The simulations showcase the satisfying positioning accuracy and clock synchronisation accuracy of the proposed method.

Robust Pilot Decontamination Based on Joint Angle and Power Domain Discrimination [PDF]

, 2016
We address the problem of noise and interference corrupted channel estimation in massive MIMO systems. Interference, which originates from pilot reuse (or contamination), can in principle be discriminated on the basis of the distributions of path angles ...

Lung Disease Detection Using Hybrid CNN‐XGBoost Classifier With New Loss Function

IET Software, Volume 2026, Issue 1, 2026.
Lung disease is one of the fatal and common illnesses, affecting many people each year through various forms such as asthma, pneumonia, and lung obstruction. Numerous diagnostic methods have been proposed, most of which rely on machine learning algorithms or simple convolutional neural networks (CNNs) that often lack sufficient accuracy.

Channel Estimation For Mimo-Ofdm Systems of Joint Angle-of-Departure (AOD) or Angle-of-Arrival (AOA)

International Journal of Innovative Technology and Exploring Engineering, 2019
Beamforming with gathering mechanical assembly displays has been considered as an engaging advancement in future remote correspondence structures. To coordinate beamforming, one has to know the angle-of-departure (AoD) or angle-of-arrival (AoA). For data disclosure, the beneficiary in like manner has to know station response.
