Exploiting AoA Estimation Accuracy for Indoor Localization: A Weighted AoA-Based Approach
IEEE Wireless Communications Letters, 2019For angle-of-arrival (AoA)-based localization methods, the AoA estimation accuracy would notably influence the localization performance. In this letter, we evaluate the estimation accuracy of different AoAs in a multipath environment and propose a weighted AoA-based localization approach.

Location Estimation by Using Multiple TDOA/AOA Measurements
2020 28th Signal Processing and Communications Applications Conference (SIU), 2020In this study, a method that predicts the location of the target source by using multiple TDOA and AOA measurements instead of single TDOA and AOA measurements is proposed in order to increase the accuracy of locating using two measuring stations. The estimation performance of this method, which was proposed with detailed simulations, was analyzed ...

Joint Channel and AoA Estimation in OFDM Systems: One Channel Tap With Multiple AoAs Problem
IEEE Communications Letters, 2021Recently, a joint channel and angle-of-arrival (AoA) estimation scheme for pilot-assisted multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) systems with digital arrays has been proposed; in that scheme, compressive sensing-based time-domain channel estimation is applied. In the scheme, it is assumed that each channel

Experimental Demonstration of AoA Estimation Uncertainty for IoT Sensor Networks [PDF]
2020 IEEE 91st Vehicular Technology Conference (VTC2020-Spring), 2020 In practice, the subspace-based algorithms such as Multiple Signal Classification (MUSIC) suffer from sensitivity to antenna-array response errors and therefore they require the assessment of the calibration gain and phase perturbations. This paper evaluates experimentally the accuracy of Angle-of-Arrival (AoA) estimation based on the MUSIC algorithm ...

Wideband AoA Estimation and Beamforming with Hybrid Antenna Array
2011 IEEE Global Telecommunications Conference - GLOBECOM 2011, 2011 High speed long range millimetre-wave (mm-wave) links can be achieved by using wideband hybrid antenna arrays of sub-arrays. However, conventional wideband angle-of-arrival (AoA) estimation and beamforming algorithms are not applicable to the wideband hybrid arrays due to the array architecture difference.

A Computationally Efficient Iterative MLE for GPS AOA Estimation
IEEE Transactions on Aerospace and Electronic Systems, 2013 This paper presents a computationally efficient algorithm for GPS signal angle of arrival (AOA) estimation based on an iterative maximum likelihood estimator (iMLE) operating on an antenna array output. The iMLE has global convergence and therefore can estimate the true AOA MLE, regardless of the initial value, and has a simple mathematical form ...

Blind AoA Estimation With Hybrid Antenna Arrays
IEEE Transactions on Wireless Communications, 2021Angle-of-arrival (AoA) information is vital for beamforming which is used to combat severe propagation loss in millimetre wave communications. Although blind AoA estimation has been extensively studied for digital array, few results were reported for hybrid array.
