Abstract

The method for estimating the direction of arrival (DOA) using a matching pursuit algorithm under reverberant conditions is discussed. The method starts with the obtaining of an array output of the delay-and-sum method and calculating the average array output in the fixed frequency range. The DOA is estimated by iteration at each step and a re-optimization of all DOA found at the earlier steps. It is suggested that the method can be improved by considering the spatial information from this method.
