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.

Controlling AoA Estimation Errors in Rician Fading via Measurement Quality Classification

IEEE Access
Angle of Arrival (AoA) estimation plays a crucial role in modern positioning systems but is often affected by errors in multipath channels. Existing methods typically lack a direct mechanism to assess the quality of the estimates, while full channel ...

Performance of Angle of Arrival Detection Using MUSIC Algorithm in Inter-Satellite Link

, 2018
An attitude of satellite is not always static, sometimes it moves randomly and the antenna pointing of satellite is harder to achieve line of sight communication to other satellite when it is outage by tumbling effect.

Predicting and Clustering Attitude‐Induced Divergence in Cross‐Array AOA Measurements for LEO Satellites

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
Example of cluster identification of attitude configurations to avoid in the attitude space (in terms of angles of roll, pitch and yaw) for a payload composed by a cross antenna array with angle of arrival technology for CubeSats platforms. ABSTRACT Satellite geolocation of radio‐frequency emitters increasingly relies on compact angle‐of‐arrival (AOA ...

Anomalous Radio-Wave Scattering from Interstellar Plasma Structures

, 2000
This paper considers scattering screens that have arbitrary spatial variations of scattering strength transverse to the line of sight, including screens that are spatially well confined, such as disks and filaments.

Beampattern-Based Tracking for Millimeter Wave Communication Systems

, 2016
We present a tracking algorithm to maintain the communication link between a base station (BS) and a mobile station (MS) in a millimeter wave (mmWave) communication system, where antenna arrays are used for beamforming in both the BS and MS.

BDALT: Bilateration and Double Anchor-based Localization Technique for Wireless Sensor Networks using Angle of Arrival (AoA) and Received Signal Strength (RSS) -A Hybrid Technique

International Journal of Engineering and Advanced Technology, 2019
Anchor based localization techniques are better and cost free alternate solutions against GPS based localization techniques in Wireless Sensor Networks (WSN) applications. Anchor based localization techniques using Zigbee technology in WSN have attracted highly in the recent years.
