Asymptotically Optimal Blind Calibration

This package contains the implementation of the blind calibration method of uniform linear arrays presented in [1]. The method is asymptotically optimal for Gaussian sources, but provides enhanced calibration even for non-Gaussian signals, by further exploiting the information contained in the second-order statistics of the measured signals. The method is “almost” linear, in the sense that except for application of simple, elementwise nonlinear operations, the estimates are computed by solving a system of linear equations.
