Universal FFT and its application.

construction and validation of translation metacognitive strategy questionnaire and its application to translation quality

like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...

A discrete universal denoiser and its application to binary images

In a recent work [I], the authors introduced a discrete uniwr.sa1 denoiser (DUDE) for recovering a signal with finite-valued components corrupted by finite-valued, nncorrelated noise. The DUDE is asymptotically optimal and universal, in the sense of asymptotically achieving, without access to any information on the statistics of the clean signal, the same performance as the best denoiser that d...

Design, Optimization, and Implementation of a Universal FFT Processor

There exist Fast Fourier transform (FFT) algorithms, called dimensionless1 FFTs, that work independent of dimension. These algorithms can be configured to compute different dimensional DFTs simply by relabeling the input data and by changing the values of the twiddle factors occurring in the butterfly operations. This observation allows us to design an FFT processor, which with minor reconfigur...
