Paper Abstract

The polyphase decomposition of a sequence is a useful tool in multirate signal processing such as in the design of computationally efficient decimators and interpolators, the design of analysis/synthesis filter banks, and the development of fast discrete transform algorithms. This paper reviews a recently introduced generalization of the polyphase decomposition concept and outlines some of its applications in the simplification of digital filtering algorithms such as the design and implementation of finite-impulse-response (FIR) digital filters, the design of decimators and interpolators, and discrete Fourier transform computations.
