Time and band limiting for matrix valued functions, an example
(2015)
The main purpose of this paper is to extend to a situation involving matrix valued orthogonal polynomials and spherical functions, a result that traces its origin and its importance to work of Claude Shannon in laying the ...
Carrier Frequency Offset Compensation for OFDMA Systems Using Circular Banded Matrices
(Planta Piloto de Ingeniería Química, 2013-07)
Orthogonal frequency division multiple access (OFDMA) is a multiuser communication technique that allocates to each user a set of orthogonal carriers. In the presence of carrier frequency offset (CFO) the orthogonality ...
Bispectrality and Time-Band-Limiting: Matrix valued polynomials
(Oxford University Press, 2018-05)
The subject of time-band-limiting, originating in signal processing, is dominated by the miracle that a naturallyappearing integral operator admits a commuting dierential one, allowing for a numerically ecient way to compute ...
Bispectrality and time-band limiting: Matrix-valued polynomials
(Oxford University Press, 2018-06)
The subject of time-band limiting, originating in signal processing, is dominated by the miracle that a naturally appearing integral operator admits a commuting differential one allowing for a numerically efficient way to ...
Time and band limiting for matrix valued functions, an example
(Natl Acad Sci Ukraine, 2015-06)
The main purpose of this paper is to extend to a situation involving matrix valued orthogonal polynomials and spherical functions, a result that traces its origin and its importance to work of Claude Shannon in laying the ...
Chapter 7: A further look at time-and-band limiting for matrix orthogonal polynomials
(World Scientific Publishing Co, 2018)
We extend to a situation involving matrix-valued orthogonal polynomials, a scalar result that originates in work of Shannon and a ground-breaking series of papers by Slepian, Landau and Pollak at Bell Labs in the 1960s. ...
Time and band limiting for matrix valued functions: An integral and a commuting differential operator
(IOP Publishing, 2017-01-09)
The problem of recovering a signal of finite duration from a piece of its Fourier transform was solved at Bell Labs in the 1960's, by exploiting a 'miracle': a certain naturally appearing integral operator commutes with ...
Clinical evaluation of proximal contacts of Class II esthetic direct restorations
(2004-11-01)
Objective: This study evaluated the effectiveness of proximal contacts in Class II restorations using two types of matrix bands (steel and polyester) with two different restoration techniques (incremental and with ...
