Journal ArticleDOI
Estimation of frequencies of multiple sinusoids: Making linear prediction perform like maximum likelihood
Donald W. Tufts,Ramdas Kumaresan +1 more
TL;DR: In this paper, the frequency estimation performance of the forward-backward linear prediction (FBLP) method was improved for short data records and low signal-to-noise ratio (SNR) by using information about the rank M of the signal correlation matrix.
Journal ArticleDOI
Estimating the parameters of exponentially damped sinusoids and pole-zero modeling in noise
Ramdas Kumaresan,Donald W. Tufts +1 more
TL;DR: In this paper, the estimation procedure presented here makes use of "backward prediction" in addition to singular value decomposition (SVD) for accurate estimation of closely spaced frequencies of sinusoidal signals in noise.
Journal ArticleDOI
Estimating the Angles of Arrival of Multiple Plane Waves
Ramdas Kumaresan,Donald W. Tufts +1 more
TL;DR: In this article, a polynomial D(z) with special properties is constructed from the eigenvectors of C, the zeros of which give estimates of the angle of arrival.
Journal ArticleDOI
Singular value decomposition and improved frequency estimation using linear prediction
Donald W. Tufts,Ramdas Kumaresan +1 more
TL;DR: LP estimation of frequencies can be greatly improved at low SNR by singular value decomposition (SVD) of the LP data matrix, as is done in Pisarenko's method and its variants.
Journal ArticleDOI
An algorithm for pole-zero modeling and spectral analysis
TL;DR: In this paper, a connection between fitting exponential models and pole-zero models to observed data is made, and the fitting problem is formulated as a constrained nonlinear minimization problem.
