Abstract

On Developing a Software Defined Radio Laboratory Course for Undergraduate Wireless Engineering CurriculumSoftware Defined Radio (SDR) represents a modern approach to radio engineering. In traditionalwireless systems, multiple chipsets that each implements a different wireless standard arerequired in a wireless device to enable communications between heterogeneous devices. WithSDR, there is a single piece of programmable hardware (with field programmable gate arrays(FPGA) on board); wireless communications waveforms and protocols are implemented insoftware, which can be uploaded to the FPGAs on-demand. As a result, SDR enables flexiblereconfiguration of wireless communication systems, more efficient access to the spectrum,coexistence and great inter-operability among heterogeneous wireless systems.SDR has great potential for both military and civilian applications, with far-reaching impact inour society. It is important to expose our undergraduate students to this advanced technology. Inaddition, the SDR platforms provide easy access to all the layers in a wireless network system,which was not possible with traditional wireless systems. Usually MATLAB simulation projectsare used in our communication system course due to the lack of access to the physical layer.With SDR, students can easily build and experiment with real wireless waveforms andapplications.In this paper, we report our experience on the development of an SDR laboratory course at theundergraduate level to enhance the Bachelor of Wireless Engineering (BWE) curriculum atAuburn University, an ABET-accredited program and first-of-its-kind in the US. With the“learning by doing” approach, we aim to enhance teaching and student learning oncommunications theory and wireless networking. We adopted an open-source platformconsisting of GNU Radio and Universal Software Radio Peripheral (USRP), which would behelpful for dissemination and adoption at other schools. The proposed SDR lab consists of thefollowing parts:(i) Preliminaries, including introduction to Linux, Gnu Radio, and the USRP platform.(ii) Analog communications, including amplitude modulation (AM) and angle modulation systems.(iii) Digital communications, including binary phase-shift keying (BPSK), Quadrature Phase Shift Keying (QPSK), intersymbol interference and eye diagram.(iv) Wireless local area networks (WLAN): including various WLAN protocols such as ALOHA, CSMA, CSMA/CA (802.11DCF) and a Polling Service Based Mac (PSMAC).(v) Cellular network: students use OpenBTS to build a Global System for Mobile communications (GSM) base station to support cellphone calls in the lab.We have developed detailed lab instructions for the nine experiments in this lab course. We alsoaim to include an open project to allow students to explore their creativity to build their owncommunication systems with help from the instructor and graduate teaching assistants. The labcourse was test-offered in Spring 2013 as ELEC 4970—Special Topics in Electrical Engineering:Software Defined Radio Lab. The Student Assessment of their Learning Gains (SALG) tool(http://www.salgsite.org/) was used to create a survey to collect feedback from students.
