Design QPSK Communication System By Software-Defined Radio (SDR)

Abstract

This paper presents the design of a QPSK communication system with Software-Defined Radio (SDR). SDR communication system is a system that uses software to control the digital signal processing (DSP) within a communication system, such as a mixer, filter, modulator and demodulator circuits, etc. This SDR communication system is flexible. and easy to update. Choose a hardware platform and software, which is USRP B210 and MATLAB, respectively. Design and test the QPSK communication system for both receiving and transmitting.
