Abstract
In this letter, we addressed the problem of estimating
the time delay and the frequencies of noisy sinusoidal signals received
at two spatially separated sensors. We employ the Propagator
Method (PM) in conjunction with the well-known MUSIC/
root-MUSIC algorithm; the proposed method would generate estimates
of the unknown parameters. Such estimates are based on the
observation and/or covariance matrices. Moreover, the PM does
not require the eigenvalue decomposition (EVD) or singular value
decomposition (SVD) of the cross-spectral matrix (CSM) of received
signals; therefore, a significant improvement in computational
load is achieved. Computer simulations are also included to
demonstrate the effectiveness of the proposed method.
