Estimation results for the real data. For the CBF, MVDR and SRP-PHAT methods, the estimation results are shown using the spatial spectrum of all frames. For the MSBL-EM and proposed SAVE-MSBL-EM method, the estimation results are shown using the weights w of all frames. All the data are normalized frame by frame. a The truth trajectory of two source. b The results of CBF based method. c The results of MVDR based method. d The results of SRP-PHAT method. e The results of MSBL-based method. f The results of the proposed method
