RAdio Logicielle pour la Formation (RALF)¶

warning. Work in progress...

The project RAdio Logicielle pour la Formation (RALF) has been carried out by the University of Toulouse/ISAE in order to promote Software Defined Radio (SDR) techniques into several engineering trainings. First of all, one can define a SDR transceiver as a generic hardware device (typically wideband with high sampling rate) where all application-related signal processing is performed in the digital domain thanks to a host computer or an embedded controller. It results in a highly flexible architecture, generally made of high-level software building blocks allowing to move from an application/or standard to an other within a tenth of second (e.g. from a GSM receiver to an FM transmitter).

In an educational point of view, SDR offers several advantages:

• cross-curricular approach involving digital communications, beamforming, computer science, networks, radio frequency electronics, embedded electronics;
• fully functional applications based on well-known standards and presented with an appropriate abstraction level;
• possible connection with research areas of the educational staff;
• source code oriented project management, more and more used in the industry (e.g. agile, eXtreme programming).
