1 November 1991 Pseudoinverse matrix methods for signal reconstruction from partial data
Author Affiliations +
The usefulness of the concept of a pseudo-inverse matrix to problems in signal processing is emphasized. It is shown how pseudo-inverse matrices can be used to describe the projection of a signal onto the subspace generated by a finite family of basis signals, which need not be linear independent. The connection to the theory of frames, the one-step POCS method, and Cunningham projection onto repetitive bases are explained, among others.
