Weakly interpolating subspaces

Numerical Functional Analysis and Optimization, 1983
A study is made of those n-dimensional subspaces G of C 0(T) which are weakly interpolating. They are more general than the classical Haar or Chebyshev subspaces, or the weak Chebyshev subspaces considered in [2]. Weakly interpolating subspaces G have the property that for each feC0(T) which has a unique best approximation g0 e G, the error f - g0 has ...

Interpolation Filter Model For Ramanujan Subspace Signals

ICASSP 2023 - 2023 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2023
Ramanujan sums have been shown to have interesting applications in signal processing. Ramanujan subspaces, Ramanujan dictionaries, and Ramanujan filter banks are useful in representing and denoising discrete-time periodic signals. In this paper, we theoretically investigate an ideal interpolation filter model for Ramanujan subspace signals wherein an ...
