Beam-Shape-Based Angle-of-Arrival Estimation in Free-Space Laser Communication
IEEE Photonics JournalA novel technique is proposed for estimating the angle-of-arrival (AOA) in free-space laser communication based on the shape of a laser beam spot on a flat surface. Two methods are introduced: one where ellipses are fitted to the intensity contour of the

Angle of Arrival Estimation for Broadband Signals: A Comparison [PDF]
IET Intelligent Signal Processing Conference 2013 (ISP 2013), 2013 This paper reviews and compares three different linear algebraic signal subspace techniques for angle of arrival estimation. These include a polynomial matrix approach to multiple signal classification (MUSIC), a parameterised spatial covariance matrix approach, and an auto-focussing based version of coherent signal subspace estimation applied to MUSIC.
