Boundary Filters for Finite-Length Signals and Time-Varying Filter Banks

Abstract

We examine the question of how to construct time-varying lter banks in the most general M-channel non-orthogonal case. We show that by associating with both analysis and synthesis operators a set of boundary lters, it is possible to make the analysis structure vary arbitrarily in time, and yet reconstruct the input with a similarly time-varying synthesis… (More)
