Software Defined Radio: USRP N210 with GNU Radio

Abstract

Driven by the increasing interest from the research community, this paper presents the current role of software defined radio (SDR) in academic and commercial applications which is helpful for the researchers, professors as well as students working in the area of signal processing and wireless communication. The authors mainly focus on universal software radio peripheral (USRP) N210 which is employed as hardware and GNU Radio as software to implement SDR for various applications that help the researchers to test and analyze various proposed techniques for different systems. Furthermore, this paper presents the implementation of basic analog/digital modulation techniques, and recent research works carried out by using SDR. This paper also presents several limitations and current usage of SDR in commercial and academic applications.
