A Novel Architecture for Radix-4 Pipelined FFT Processor using Vedic Mathematics Algorithm

Abstract

The FFT processor is a critical block in all multi-carrier systems used primarily in the mobile environment. The portability requirement of these systems is mainly responsible for the need of low power FFT architectures. In this study, an efficient addressing scheme for radix-4 64 point FFT processor is presented. It avoids the modulo-r addition in the… (More)
