In this paper, the wideband Capon cepstrum weighted l2, 1 minimization algorithm (WB-CW l2, 1) is presented for wideband direction of arrival (DOA) estimation using an acoustic array. The problem of wideband DOA estimation is converted into the estimation of the sparsity pattern of a jointly sparse signal and then solved by the weighted l2, 1 norm minimization. WB-CW l2, 1 uses the Capon cepstrum...
In this paper, an approach of Estimating Signal Parameter via Rotational Invariance Techniques (ESPRIT) under sensor gain-phase uncertainties errors is reprensented with the Direction Of Arrival (DOA) and the Direction Of Departure (DOD) is considered. The approximate expressions for the Root Mean Square Error (RMSE) of the ESPRIT DOA and DOD estimation under random sensor perturbations are derived...
