Toeplitz-like structures and matrix equations encountered in stochastic modeling

In this thesis, we study methods for computing the invariant probability measure for certain quasi-birth-and-death Markov chains. In particular, we consider the situation of a double QBD, whose transition matrix has the infinite, block-tridiagonal and ...

Toeplitz Covariance Matrix Estimation for Adaptive Beamforming and Ultrasound Imaging

, 2012
In recent years, adaptive beamformers have been researched more extensively, to be able to use it in the application of medical ultrasound imaging. The adaptive beamformers can provide a higher resolution and better contrasts in the resulting images than

The asymptotic spectra of banded Toeplitz and quasi-Toeplitz matrices

, 1991
Toeplitz matrices occur in many mathematical, as well as, scientific and engineering investigations. This paper considers the spectra of banded Toeplitz and quasi-Toeplitz matrices with emphasis on non-normal matrices of arbitrarily large order and ...
