摘要: A new DOA (direction of arrival) estimation method is proposed for 3D (three-dimensional) multiple source signals using independent component analysis (ICA). The travel and mix in a reverberant environment are observed at sensor array. These separated based on the DOAs estimated. This can deal with up to number sensors while conventional subspace analysis, such as well-known MUSIC algorithm, merely be applied those cases where less than that sensors. two step also improve accuracy dispersion estimated DOAs. Experimental results reveal better algorithm from perspective small dispersion.
