WebThe problem of direction of arrival (DOA) estimation with a circular microphone array has been addressed with classical source localization methods, such as the model-based methods and the param etric methods. These methods have an advantage in estimating the DOAs in a blind manner, i.e. with no (or limited) prior knowledge about the sound sources. WebTo overcome the conflict of low frequency resolution issue for the microphone array with small aperture and spatial aliasing issue caused by the microphone array with large aperture, this paper adopts a uniform concentric circular array topology and proposes an improved method based on delay and sum beamforming algorithm to realize the multiple ...
