Software Defined Integrated RF Frontend Receiver Design

Abstract

AbstractSoftware Defined Radio (SDR) technology uses a generic hardware platform supported by software modules to accommodate different communication standards, frequency bands and modulation schemes. In today’s world, integration of various mobile communication standards like Code Division Multiple Access (CDMA), Global System for Mobile communication (GSM), Wideband CDMA (WCDMA) and Worldwide Interoperability for Microwave Access (WIMAX) is the need of the hour. This paper deals with the concepts and procedures involved in designing software defined integrated radio frequency (RF) frontend receiver which can be configured to support different technologies like GSM, CDMA and WCDMA. In a three band case, a new band pass sampling algorithm is proposed to evaluate valid sampling frequency ranges and corresponding intermediate frequencies for multiple standards. The simulation results show that the algorithm developed and the software defined integrated RF frontend receiver design proposed in this paper give good performance.KeywordsBand Pass SamplingBase Transceiver StationInteroperabilityModulationNumerically Controlled OscillatorReconfigurable architecture and Software Defined Radio
