Abstract

We devise a new subspace method for estimating the differential time delay of a signal received at two separated sensors as well as the frequencies of the source signal, assuming that it consists of multiple sinusoids. The time delay and frequency estimates are related to the eigenvalues and eigenvectors of a matrix obtained from the covariances of the received signals. The effectiveness of the proposed algorithm is demonstrated via computer simulations using sinusoidal signals as well as real speech data
