Array Correlation Matrix Element Properties and Their Application to Low-Cost DOA Estimation Koichi ICHIGE Yu IWABUCHI Publication IEICE TRANSACTIONS on Communications Vol.E99-B No.8 pp.1859-1866 Publication Date: 2016/08/01 Online ISSN: 1745-1345 DOI: 10.1587/transcom.2015EBP3465 Type of Manuscript: PAPER Category: Antennas and Propagation Keyword: direction of arrival estimation, array signal processing, correlation matrix, Full Text: PDF(573.4KB)>>
Summary: We study the correlation matrix element properties in array signal processing and apply them to a Direction-Of-Arrival (DOA) estimation problem of coherent or highly-correlated sources for a Uniform Linear Array (ULA). The proposed algorithm is generally based on the relation between the elements of the array correlation matrix and does not need an eigendecomposition, iteration, or angular peak-search. The performance of the proposed method was evaluated through a computer simulation. | |||||
