Software radio, enabling technology for migration to third generation of mobile communication systems

Summary form only given. The term 'software radio' is not precisely defined in general speech. Here, we understand software radio as being a reconfigurable hard- and software platform which can be adapted to special requirements, e.g. different standards or services, simply by downloading the appropriate software. Software radio embraces everything from a flexible terminal equipment through adaptive base stations and base station controllers to flexible fixed network structures.
