Time and band limiting for matrix valued functions : an integral and a commuting differential operator
(2017)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 ... -
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 ...
