Efficient realization of the block frequency domain adaptive filter

In many frequency domain adaptive lters Fast Fourier Fourier Transforms FFTs are used to transform sig nals which are augmented with zeros The overall com putational complexity of these adaptive lters is mainly determined by these windowed FFTs rather than by the ltering operation itself This contribution presents a new way of calculating these windowed FFTs ef ciently In addition a method is d...

Implementing super-efficient FFTs in Altera FPGAs

Abstract : In this article, an alternative method is proposed to compute a fast Fourier transform (FFT) on Altera FPGAs. This method is using the Altera FFT intellectual property (IP) core, but it is more efficient than the direct use of the Altera FFT IP core, in the sense that the processing time or the resources can be reduced. For the FPGA user, the implementation of the proposed method is ...

Notes on FFT-based differentiation

A common numerical technique is to differentiate some sampled function y(x) via fast Fourier transforms (FFTs). Equivalently, one differentiates an approximate Fourier series. Equivalently, one differentiates a trigonometric interpolation. These are also known as spectral differentiation methods. However, the implementation of such methods is prey to common confusions due to the aliasing phenom...

Soft Systems Methodology for Implementing Clinical Practice Guidelines in A General Hospital: A study protocol

Background: It is notoriously challenging to implement evidence-based care and to update and improve health care policy. Adhering to evidence-based Clinical Practice Guidelines (CPGs) serves as the driving force behind making decisions based on the best evidence and making efforts for improving the quality of patient care and outcomes. Despite requiring Iranian hospitals to implement CPGs in Ja...
