Sampling Associated with a Unitary Representation of a Semi-Direct Product of Groups: A Filter Bank Approach
An abstract sampling theory associated with a unitary representation of a countable discrete non abelian group <i>G</i>, which is a semi-direct product of groups, on a separable Hilbert space is studied. A suitable expression of the data samples, the use of a filter bank formalism and th...
