Abstract

This paper presents a technique for estimating the number of sources based on the eigenvectors of the covariance matrix of received signal at an antenna array when some minimal information about the directions of arrival of received signals of sources is supplied by using a spectral estimation method such as MVDR. The proposed technique is designated the eigenvector order estimation technique (EOET). EOET outperforms AIC, MDL and GDE techniques in practice and provides comparable detection sensitivity as AIC, MDL, and GDE in computer-based simulated sources.
