Abstract: In this paper we study the impact of polynomial or broadband subspace decompositions on any subsequent processing, which here uses the example of a broadband angle of arrival estimation ...
Journal of Operator Theory, Vol. 53, No. 1 (Winter 2005), pp. 197-220 (24 pages) It is known that if AB – BA is quasinilpotent for every A and B in a multiplicative semigroup 𝒮 of compact operators ...
Abstract: In sensor array applications, it can be advantageous to project data onto a given signal subspace, for example, to improve the SNR or as part of direction finding algorithms. In the ...
ABSTRACT: Let A be the linear transformation on the linear space V in the field P, V λ i be the root subspace corresponding to the characteristic polynomial of the eigenvalue λ i , and W λ i be the ...
Shift-invariant spaces form a fundamental class of function spaces where elements can be represented as linear combinations of translates of one or more generating functions. This concept is pivotal ...
