A Simple Cross Correlation Switched Beam System (XSBS) for Angle of Arrival Estimation
IEEE Access, 2017 We propose a practical, simple and hardware friendly, yet novel and 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 ...

Stochastic framework for evaluating the effect of displaced antenna elements on DOA estimation [PDF]
, 2017 We establish a statistical framework for investigating the influence of correlated random displacements of antenna elements in a uniform circular antenna array (UCA) on the distribution of direction-of-arrival (DOA) estimates. More specifically, we apply

Power-Based Direction-of-Arrival Estimation Using a Single Multi-Mode Antenna
, 2017 Phased antenna arrays are widely used for direction-of-arrival (DoA) estimation. For low-cost applications, signal power or received signal strength indicator (RSSI) based approaches can be an alternative. However, they usually require multiple antennas,

Spatially localized direction of arrival estimation
Proceedings : European Conference on Noise Control, 2018 Direction-of-arrival (DOA) estimation is a fundamental area of research in the field of array processing, as it applies in a variety of areas, including: sound field analysis, spatial sound reproduction and spatial filtering. There exists a plethora of DOA estimating algorithms, which all vary in terms of accuracy and computational complexity.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background L‐asparaginase is a critical component in treatment protocols for pediatric acute lymphoblastic leukemia. Acute pancreatitis reactions can necessitate delays and, in some cases, discontinuation of L‐asparaginase, which compromises outcomes.
