Abstract: In this paper, authors propose a spatial difference Toeplitz algorithm for effective direction of arrival (DOA) estimation of mixed signals that contain both uncorrelated and coherent ...

Abstract: We describe a new fast Fourier transform (FFT)-based algorithm to expedite matrix-vector multiplies involving multilevel block-Toeplitz (BT), or T/sub f/ /sup M/ matrices. Matrices of this ...

Newton's iteration is modified for the computation of the group inverses of singular Toeplitz matrices. At each iteration, the iteration matrix is approximated by a matrix with a low displacement rank ...

In this paper, we investigate the conditions under which the Toeplitz composition operator on the Hardy space 𝓗² becomes complex symmetric with respect to a certain conjugation. We also study various ...
