The Research of Software Definition Radio (SDR) Based on Hardware Platform

Wang Qun-sheng

Abstract

The software will realize more functions based on common hardware platform.It is convenient to improve the performance of the whole system,meanwhile,different systems can be interlinked and compatible.This paper analyzes the sampling theory,multi-rate signal processing theory and digital signal demodulation on basis of SDR.The mathematics model of the single channel transmitter is established,meanwhile,the primary application of SDR is also studied in smart antenna.Finally,this paper introuduces the exsiting problem and the future of SDR.
