Analysis of DDS Frequency Characteristic for Polar Transmission based on Software Defined Radio

Abstract

In this paper, we implemented polar transmitt converter based on software for next generation digital wireless communication system. The implemented converter converted from rectangular to polar by CORDIC algorithm, and be made up of sweep for DDS output frequency using software control. The implemented converter shows can frequency control up to 1.16GHz within DDS frequency control range by software control. it means that transmitter can be control of varied blocks such as gain, phase, output and etc.. The implemented converter can be applied digital wireless communication system based on SDR.
