Minimum Dispersion Beamforming for Non-Gaussian Signals
Abstract
Most of the existing beamforming methods are based on the Minimum Variance (MV) criterion. The MV approach is statistically optimal only when the signal, interferences and the noise are Gaussian-distributed. However, non-Gaussian signals arise in a variety of practical applications. In this paper, Minimum Dispersion Distortionless Response (MDDR) beamforming, which minimizes the $\ell_p$-norm of the output while constraining the desired signal …
