Abstract
This paper demonstrates how the popular overlap-save (OS) fast convolution filtering technique can be extended to create a flexible and computationally efficient bank of filters, with frequency translation and decimation implemented in the frequency domain. The paper also provides some tips for choosing appropriate fast Fourier transform (FFT) size. It also presents implementation guidance to streamline this powerful, multichannel filtering, down-conversion and decimation process
