✦ Synopsis

This paper describes the tradeoffs and design method for a polyphase filter bank implemented in field programmable gate array technology. Consideration is given to the minimization of required hardware resources by careful choice of the FFT approach, multiplier implementation, and wordlength optimization. These choices are made subject to maintaining specified output performance. Finally, the sigma-delta technique is examined to further reduce the computational complexity. 1998 Academic Press

We consider implementation of operators via filter banks in the framework of the multiresolution analysis. Our method is particularly efficient for convolution operators. Although our method of applying operators to functions may be used with any wavelet basis with a sufficient number of vanishing m

## Abstract In many applications of filter banks, a low‐delay filter bank in which the system delay is small is desirable. In this paper, two new design methods are proposed for low‐delay perfect‐reconstruction filter banks. First, a design method is described for a two‐channel perfect‐reconstructi

## Abstract A method of multimedia transmission in wireless communication is to apply the frequency‐division multiplex scheme, in which the bandwidth is assigned flexibly according to the signal transmission rate. The purpose of this paper is to develop a system in which multimedia wireless transmi

Half-band filters are a class of important filters among digital filters, and have been widely used in many applications such as filter banks and wavelets. The conventional methods are mainly concerned with FIR half-band filters with exactly linear phase. However, the exactly linear phase filters ha
