Cross Dipole Antennas Solution for Angle of Arrival Estimation

Wideband vs. Narrowband Angle of Arrival Estimation

Angle of Arrival (AoA) estimation that applies wideband channel estimation is superior to the narrowband MUSIC (multiple signal classification) approach, even when averaging its results over the entire relevant band. This work reports the results of indoor AoA estimation based on wideband propagation channel measurements taken over a uniform linear antenna array. The measurements were carried o...

Radio Interferometric Angle of Arrival Estimation

Several localization algorithms exist for wireless sensor networks that use angle of arrival measurements to estimate node position. However, there are limited options for actually obtaining the angle of arrival using resource-constrained devices. In this paper, we describe a radio interferometric technique for determining bearings from an anchor node to any number of target nodes at unknown po...

Two Dimensional Angle of Arrival Estimation

We present a new method for the estimation of two dimensional (2D) angles of arrival (AOAs), namely, azimuth and incidence angles of multiple narrowband signals of same frequency in the far field of antenna array. In this report, we propose an algorithm which uses an L-shape array configuration [1]. We extend the polynomial based approach presented in [2] to two dimensional AOA estimation. We C...
