K. Nayebi et al., ON THE DESIGN OF FIR ANALYSIS-SYNTHESIS FILTER BANKS WITH HIGH COMPUTATIONAL-EFFICIENCY, IEEE transactions on signal processing, 42(4), 1994, pp. 825-834
This paper presents an effective design algorithm for analysis-synthes
is filter banks with computationally efficient structures. Although a
wide variety of implementation structures can be accommodated, the foc
us of this paper is on cosine modulated filter banks. The design proce
dure is based on a time domain formulation of analysis-synthesis filte
r banks in which each individual channel filter is constrained to be a
cosine modulated versions of a baseband filter. The resulting filter
banks are very efficient in terms of computational requirements and ar
e relatively easy to design. A unique feature of this approach is that
relatively low reconstruction delays can be imposed on the system. A
discussion of the associated computational properties of the designed
systems and some design examples are included.
