Systolic array implementations for Chebyshev nonuniform sampling

Abstract

A Chebyshev-type interpolation function (CTIF) based on Chebyshev nonuniform sampling is developed, and some important properties of the CTIF are discussed. It has been demonstrated that the concept of signal reconstruction from the nonuniform samples can be described clearly by using the CTIF. Two implementation schemes, a time domain structure and a transformed domain structure using systolic array architecture for this method, are also discussed. The schemes have the advantages of simplicity, regularity, and fast reconstruction, and they are suitable for data compression.<>
