Direction of arrival estimation using the rotating equatorial microphone

Frontiers in Signal Processing
Introduction: Direction of arrival (DOA) estimation of sound sources is an essential task of sound field analysis which typically requires two or more microphones. In this study, we present an algorithm that allows for DOA estimation using the previously

An Effective CS-BP Algorithm for 2-D DOA Estimation

, 2011
The bandwidth of the direction of arrival (DOA) estimation requires high sampling rate which extends the current analog to digital converter capacity. The paper presents an effective basis pursuit (BP) algorithm based on compressive sensing (CS) signals,
