Implementation of a novel digital Front end for software defined radio System

Abstract

Software Defined Radio SDR technology provides a platform newlinethat supports advances in the existing systems and rapid deployment of the newlinedeveloping systems with substantial future proofing It makes the systems newlinehardware generic and hence move all the waveform specific tasks into newlinesoftware As every service provider and equipment manufacturer demand newlinetheir own standard an universal receiver with virtually no restrictions on newlinebandwidth selectivity frequency range and modulation schemes is needed newlineFront end processing is the functional area of the end user device newlinethat consists of necessary physical air or propagation medium interface the newlinefront end radio frequency processing frequency conversions and newlinemodulation demodulation processing One of the major challenges in newlinerealization of the universal SDR is the lack of a unified front end that can newlineserve numerous standards newline newline
