Multi-Source Position and Direction-of-Arrival Estimation Based on Euclidean Distance Matrices
EDM- and Gram-matrix methods for multi-source localization optimize one distance variable per source for positions and none for DOAs, outperforming SRP beamforming in accuracy and runtime for two sources in noisy reverberant conditions.
