A novel ULA-based geometry for improving AOA estimation
EURASIP Journal on Advances in Signal Processing, 2011 Due to relatively simple implementation, Uniform Linear Array (ULA) is a popular geometry for array signal processing. Despite this advantage, it does not have a uniform performance in all directions and Angle of Arrival (AOA) estimation performance ...

Time-multiplexed AoA Estimation and Ranging
2023 International Conference on Localization and GNSS (ICL-GNSS), 2023 A joint angle-of-arrival (AoA) and ranging estimation scheme for ultra-wideband devices is presented and experimentally evaluated. Instead of using N parallel receive chains, antenna elements are sequentially switched to the receiver, i.e., time-multiplexed.

A Simple AoA Estimation Scheme
CoRR, 2014 We propose an intuitive, simple and hardware friendly, yet surprisingly novel and efficient, received signal's angle of arrival (AoA) estimation scheme. Our intuitive, two-phases cross-correlation based scheme relies on a switched beam antenna array, which is used to collect an omni-directional signal using few elements of the antenna array in the ...

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 ...
