Single-Antenna AoA Estimation with UWB Radios
2021 IEEE Wireless Communications and Networking Conference (WCNC), 2021Ultra-wideband (UWB) is becoming a major localization technology enabler for the indoor environment. Traditional localization systems rely on time-of-arrival (ToA)-based methods such as two-way ranging (TWR) and time difference of arrival (TDoA). Such solutions cannot scale due to interference from multiple devices sharing the same part of the wireless

MLE and RBF for AOA Estimation in A Multipath Environment
, 1995 The problem of estimation of angle-of-arrival (AOA) in multipath environments is addressed in this thesis. In particular, two new estimation techniques are developed. The first technique is based on the maximum likelihood estimation (MLE). This algorithm is unique in that a highly deterministic multipath signal model is used when formulating the ...

AoA Estimation for OAM Communication Systems With Mode-Frequency Multi-Time ESPRIT Method
IEEE Transactions on Vehicular Technology, 2021 Radio orbital angular momentum (OAM) communications require accurate alignment between the transmit and receive beam directions. Accordingly, a key feature of OAM receivers is the ability to reliably estimate the angle of arrival (AoA) of multi-mode OAM ...

A Unified Estimator for Source Positioning and DOA Estimation Using AOA
2018 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2018Angles of Arrival (AOAs) are popular measurements to locate a signal source. They can yield a position if the source is near the sensors or a DOA if it is far away. Point positioning and DOA localization require different estimators and the knowledge if the source is near or far is needed.

A Localization Algorithm Based on V2I Communications and AOA Estimation
IEEE Signal Processing Letters, 2017Motivated by safety applications in urban vehicular scenarios, where GPS does not typically provide the required positioning accuracy, a GPS-free localization technique that exploits vehicle-to-infrastructure communications is proposed. In particular, it provides for a vehicle to opportunistically use the beacon packets received from a roadside unit ...

Itetative AOA Estimation of Coherent Signals
TENCON 2007 - 2007 IEEE Region 10 Conference, 2007The angles-of-arrival (AOA) estimation and beam- forming by an array antenna plays important roles in MIMO communication systems. In multipath environment, almost conventional subspace approaches with or without the eigendecomposition adopt the spatial smoothing (SS) using multiple subarrays.

AOA estimation for coexisting UWB signals with multipath channels
2014 International Conference on Telecommunications and Multimedia (TEMU), 2014The applications of location-based service (LBS) grow rapidly and draw significant research attention recently. As the advance of localization technology, not only the LBS can be applied outdoors but also in indoor environments with abundant multipath channels.
