New Direction-of-Arrival-Based Source Localization Algorithm for Wideband Signals

Source localization for wideband signals using near-field acoustic sensor networks has been drawing a lot of research interest recently. In this paper, we would like to tackle the source localization problem based on the realistic assumption where the sources are corrupted by spatially-non-white noise. We explore the respective limitations of our recently proposed algorithm, namely EM source localization algorithm, and design a new direction-of-arrival (DOA) estimation based (DEB) source localization algorithm. The simulation results demonstrate that our proposed DEB algorithm significantly outperforms the previous EM method.
