Adaptive AoA Estimation and Beamforming with Hybrid Antenna Arrays [PDF]
2009 IEEE 70th Vehicular Technology Conference Fall, 2009 A new type of hybrid antenna array consisting of analogue subarrays followed by a digital beamformer is proposed for practical implementation of long range high data rate millimetre wave communications systems. An adaptive algorithm, referred to as the differential beam search (DBS), is proposed for the angle of arrival (AoA) estimation to control the ...

Analysis of CRLB for AoA estimation in Massive MIMO systems
2021 IEEE 32nd Annual International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC), 2021 Massive MIMO systems provide high angular resolution in the next generation of wireless systems. This opportunity can be used to estimate the location of user terminals (UTs) accurately. In this paper, we analyze the Cramer-Rao lower bound (CRLB) of planar antenna arrays in Massive MIMO systems for Angle of Arrival (AoA) estimation.

AoA Estimates for LPWAN Technologies: Indoor Experimental Analysis
2021 15th European Conference on Antennas and Propagation (EuCAP), 2021 In this paper, we present an experimental analysis of the Angle of Arrival (AoA) estimation accuracy in an indoor environment. We utilized an AoA estimation system that is suitable for Low Power Wide Area Network (LPWAN) technologies. The AoA estimation system constituted 8 antenna elements that are distributed as Uniform Linear Array (ULA) antenna ...

Two-Dimensional AOA Estimation Based on a Constant Modulus Algorithm [PDF]
International Journal of Antennas and Propagation, 2017 We propose a two-dimensional (2D) angle of arrival (AOA) estimator using the algebraic constant modulus algorithm (ACMA). This algorithm was originally introduced to estimate the one-dimensional (1D) AOA.

Sparsity-based AOA Estimation for Emitter Localization
TELKOMNIKA Indonesian Journal of Electrical Engineering, 2012 Angle of arrival (AOA) is able to achieve high accuracy when the antenna arrays are deployed much closer to the emitter. However, spatial resolution problem still exists. This paper presents a novel AOA estimation method called sparsity angle sensing (SAS) to improve the resolution.
