Abstract:
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.
