The presence of reflecting surfaces inside an enclosure is generally known to have an adverse effect in acoustic source localization and Direction of Arrival (DOA) estimation performance. In this paper, we focus on the problem of indoor multi-source DOA estimation along the horizontal plane, considering a circular sensor array which is placed just in front of one of the vertical walls of the room. We present a modification in the propagation model, which traditionally accounts for the direct… CONTINUE READING
