Evaluation of the angle of arrival based techniques

2013 8th IEEE Design and Test Symposium, 2013
In this work we present the angle of arrival estimation techniques and their comparison at different values of SNR using a 5 element UCA. The techniques that have been considered include phase interferometry, Multiple Signal Classification and covariance.

On Angle-of-Arrival and Time-of-Arrival Statistics of Geometric Scattering Channels

IEEE Transactions on Vehicular Technology, 2009
This paper proposes a hyperbolic distribution to model the distribution of random scatterers between a base station (BS) and the user equipment (UE) in multipath mobile environments. New hyperbolic angle-of-arrival (AoA) probability density function (pdf), power azimuth spectrum (PAS), time-of-arrival (ToA) pdf, and power delay spectrum (PDS) are ...

RF angle of arrival-based node localisation

International Journal of Sensor Networks, 2011
Several localisation algorithms exist for wireless sensor networks that use angle of arrival measurements to derive node position. However, there are limited options for actually obtaining the angle of arrival using resource-constrained devices. In this paper, we describe a technique for determining node bearings based on radio interferometric angle of

Robust Navigation Using Angle of Arrival Measurements

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation
The majority of conventional radionavigation systems are based on Time of Arrival (TOA) measurements of RF signals. By far the most common method is pseudoranging, mainly a result of the undisputed success of Global Navigation Satellite Systems (GNSS) as a ubiquitous technology, especially in aviation.
