On decoding of digital data sent over a noisy MIMO channel
Andrei Osipov
The transmission of digital data is one of the principal tasks in modern wireless communication. Classically, the communication channel consists of one transmitter and one receiver…
Some Generalizations of the Hellinger Theorem for Second Order Difference Equations with Matrix Elements
A. S. Osipov
We obtain several generalizations the Hellinger theorem about solutions of difference equations: instead of second order equations and -solutions, we consider second-or…
On the evaluation of prolate spheroidal wave functions and associated quadrature rules
Andrei Osipov, Vladimir Rokhlin
As demonstrated by Slepian et. al. in a sequence of classical papers, prolate spheroidal wave functions (PSWFs) provide a natural and efficient tool for computing with bandlimited…
Detailed analysis of prolate quadratures and interpolation formulas
Andrei Osipov, Vladimir Rokhlin
As demonstrated by Slepian et. al. in a sequence of classical papers, prolate spheroidal wave functions (PSWFs) provide a natural and efficient tool for computing with bandlimited…
Evaluation of small elements of the eigenvectors of certain symmetric tridiagonal matrices with high relative accuracy
Andrei Osipov
Evaluation of the eigenvectors of symmetric tridiagonal matrices is one of the most basic tasks in numerical linear algebra. It is a widely known fact that, in the case of well sep…
Certain upper bounds on the eigenvalues associated with prolate spheroidal wave functions
Andrei Osipov
Prolate spheroidal wave functions (PSWFs) play an important role in various areas, from physics (e.g. wave phenomena, fluid dynamics) to engineering (e.g. signal processing, filter…
