Welcome to the main wiki of the RALF project. You will find below a brief description of the project, few notes on its organization and general documentation on hardware/software tools. As explained below in details, this forge allows per-project spaces providing various services such as ticket management, source versioning (Git), wiki, forums, full backups and total web-based administration...

Organization¶

Description of the project¶

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/standard to an other within a tenth of second.

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;
• well suited to new teaching methods (e.g. project based, active, flipped teaching...);
• possible connection with research topics (from a simulator to a demonstrator);
• source code oriented project management, more and more used in the industry (e.g. agile, eXtreme programming).

Examples of applications (to be developed):

• aeronautic (ACARS, VDL mode 2, ADS-B, HFDL...);
• satellite (NOAA APT, DVB-S...);
• cellular (GSM, UMTS, LTE, POCSAG...);
• home automation (CCIR...);
• amateur radio (SSB, APRS, AMTOR...);
• audio and video broadcast (FM, DVB-T, DRM...);
• direction finding (AOA, TOA...);

Members and partners¶

The project is currently hosted and managed by ISAE. It includes several members from the University of Toulouse: ENAC, ENSEEIHT, INSA, ISAE, UPS. It has been funded by the University of Toulouse (23 k€) and ISAE (13 k€).

Equipments and softwares¶

The project is split into two main components:

• a mobile part consisting in a loan of SDR transceivers to the project members;
• a fully equipped platform hosted at ISAE (SDR transceivers, desktop computers, signal analyzers and generators, rooftop antennas).

Several software environments are available depending
