Sparse Covariance Fitting Method for Direction of Arrival Estimation of Uncorrelated Wideband Signals
We propose a new direction of arrival estimation method for wideband uncorrelated signals. The wideband signals are first decomposed into narrowband signals. A group sparse Lasso formulation is proposed that jointly fits the powers of the signals using overcomplete dictionaries of the directions of...
