Abstract:
Over the last decade or so, radio receivers and transmitters have more and more been constructed using digital rather than analog technology.
Consequently, their properties and performance are increasingly determined by rather than hardware. 
This trend will have consequences for wireless communication equipment in the future.
Software-defined radio is not a subject of research within DACS, so the presentation will be an introductory one. After a brief discussion of 
some fundamentals of radio technology (for those who do not have an electrical engineering background), the increasing digitization of 
radio equipment will be illustrated, and the advantages, new possibilities, and limitations of digital radio technology will be discussed. 
Finally, a live demonstration will be given of an actual software-defined radio system running on a normal PC.
