An Affordable Software Defined Radio

Abstract

This paper discusses the utilization of a relatively inexpensive wideband radio receiver in combination with a digital downconverter (DDC) based data recorder to capture and record real world radio signals. The resulting in-phase (I) and quadrature (Q) data les are then imported into MATLAB for processing. This batch processing of real world radio signals allows for a tremendous amount of classroom exibility in the discussion of software de ned radio topics.

LabVIEW, the USRP, and their Implications on Software Defined Radio

“…Universities have been teaching software defined radio (SDR) courses and related communication system/signal processing topics for a number of years [1][2][3][4][5][6][7][8][9][10][11][12][13] . Unfortunately, these courses typically experience one or more of the following problems: a.…”
