Polyphase decomposition of a sequence was advanced to develop computationally efficient interpolators and decimators, and has also been used to design computationally efficient quadrature-mirror filter banks. The polyphase decomposition represents a sequence into a set of sub-sequences, called polyphase components. However, the polyphase components do not exhibit any spectral separation. In this talk, we first review the concept of structural subband decomposition, a generalization of the polyphase decomposition, which decomposes a sequence into a set of sub-sequences with some spectral separation that can be exploited advantageously in many digital signal processing applications. We then outline some of the applications of the structural subband decomposition, such as, efficient design and implementation of FIR digital filters, development of computationally efficient decimators and interpolators, subband adaptive filtering, and fast computation of discrete transforms.

Dr. Sanjit K. Mitra received the B.Sc. (Hons.) degree in Physics from the Utkal University, India in 1953, M.Sc. (Tech.) degree in Radio Physics & Electronics from the University of Calcutta, India in 1958, and his M.S. and Ph.D. degrees in Electrical Engineering from the University of California, Berkeley, California in 1960 and 1962, respectively. He joined the Ming Hsieh Department of Electrical Engineering, University of Southern Californi as the Stephen and Etta Varra Professor in July 2006. He has published over 640 papers in the areas of analog and digital signal processing, and image processing. He has also authored and co-authored twelve books, and holds five patents.
