Abstract
A method includes generating a correlation vector of baseband-signal vectors based upon signals received from a plurality of sensor devices, generating a generalized Hankel matrix R representing a covariance matrix to which a spatial averaging is applied based upon the correlation vector, generating a kernel matrix Ω, which is a projection matrix onto noise subspace, by performing linear operation using submatrices Rand Rof the generalized Hankel matrix R, generating a kernel matrix Ω, which is orthogonal with the kernel matrix Ω, and estimating a direction of arrival of a signal based upon the kernel matrices Ωand Ω.
