Application of the Levenberg-Marquardt Scheme to the MUSIC Algorithm for AOA Estimation
We note that the cost function of the MUSIC (multiple signal classification) algorithm is quadratic in an array vector and that it can be expressed in a least squares form. Based on this observation, we present a rigorous Levenberg-Marquardt (LM) formulation of the MUSIC algorithm for simultaneous e...
