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.
