Angle of arrival estimation for broadband signals : a comparison [PDF]

open access: yes, 2013
This paper reviews and compares three different linear algebraic signal subspace techniques for angle of arrival estimation. These include a polynomial matrix approach to multiple signal classification (MUSIC), a parameterised spatial covariance matrix ...

Low-Complexity Wideband Interference Mitigation for UWB ToA Estimation

open access: yesSensors, 2023
Reliable time of arrival (ToA) estimation in dense multipath (DM) environments is a difficult task, especially when strong interference is present. The increasing number of multiple services in a shared spectrum comes with the demand for interference ...

A Simple Angle of Arrival Estimation System [PDF]

open access: yes2017 IEEE Wireless Communications and Networking Conference (WCNC), 2017
We propose a practical, simple and hardware friendly, yet novel and very efficient, angle of arrival (AoA) estimation system. Our intuitive, two-phases cross-correlation based system requires a switched beam antenna array with a single radio frequency chain. Our system cross correlates a reference omni-directional signal with a set of received directed

Broadband angle of arrival estimation methods in a polynomial matrix decomposition framework [PDF]

open access: yes, 2013
A large family of broadband angle of arrival estimation algorithms are based on the coherent signal subspace (CSS) method, whereby focussing matrices appropriately align covariance matrices across narrowband frequency bins.

An Alternative Approach for Angle of Arrival Estimation [PDF]

open access: yesEngineering and Technology Journal, 2015
The Multiple Signal Classification (MUSIC) algorithm is the most popular algorithm to estimate the Angle of Arrival (AOA) of the received signals. This algorithm is based on the calculation of thermal noise Eigen values and their corresponding Eigen ...
