Approximation of stationary processes and Toeplitz Spectra
Giorgio Picci, Bin Zhu
We study the approximation of stationary processes by a simple class of purely deterministic signals. This has an analytic counterpart in the approximation of symmetric positive de…

Line Spectrum Representation for Vector Processes With Application to Frequency Estimation
Bin Zhu
A positive semidefinite Toeplitz matrix, which often arises as the finite covariance matrix of a stationary random process, can be decomposed as the sum of a nonnegative multiple o…

M-Spectral Estimation: A Flexible Approach Ensuring Rational Solutions
Bin Zhu, Augusto Ferrante, Johan Karlsson +1
This paper concerns a spectral estimation problem for multivariate (i.e., vector-valued) signals defined on a multidimensional domain, abbreviated as M. The problem is posed as…
