Enhanced Fault Tolerant Parallel FFTs UsingParseval Checks and Error Correction Codes: A Study

Abstract

Reliability of mission critical systems is aweighty criterion for any system and is achieved by suitablefault detection techniques. Digital filters are most oftenintegrated in modern digital signal processing systems for theprocessing of signals.In few utilizations, apossible activity is that use of algorithmic based fault tolerance(ABFT) approaches that are endeavor and action of recursivequalities in identify as well as rectify faults. Communicationsand Signal processing utilities are more compatible toalgorithmic based fault tolerance. A few key building blocks indevices are FFTs. Numerous secured techniques recommended forrecognize as well as rectify faults in FFTs. Amidst of techniques,most probable utilization of Sum of squares or parseval check is themost generally glorious. At a recent time, one method employsthat put into effect of fault tolerance projected over similarfilters. During irregularity, the system first implemented forlookout Fast Fourier Transforms
