Future Mobile Communications Systems

Future wireless communication systems promise high data rates even when the mobile user is travelling at high speeds (in the car or on the train). Multiple antenna systems will therefore play a key role in future mobile communication systems.

Highly accurate channel models are crucial for the development of effective MIMO systems. The propagation behaviour of MIMO signals is commonly described through geometrical-stochastic channel models. The expected requirements of future systems represent a scientific challenge and there is an urgend need for new models to be developed for time-variant transmission channels.

The Future Mobile Communications Systems project is promoted by the WWTF (Vienna Science and Technology Fund - Wiener Wissenschafts-, Forschungs- und Technologiefonds) and will be accomplished in the context of cooperation with the ftw. Carried out by the Forschungszentrum Telekommunikation Wien (Telecommunications Research Centre Vienna) and the TU-Wien, Institut für Analysis und Scientific Computing (Technical University of Vienna Institute for Analysis and Scientific Computing). New mathematical methods are to be designed, which will permit high data rates in future communication systems for users moving at high travelling speeds. We intend to achieve wave propagation models via wave equations for mobile links, which are determined by numerous splitters. On the basis of the results we will develop new transmission procedures and corresponding time-variant channel forecasting and detection procedures. The real time capability of the resulting algorithms is the focus of attention and is to be achieved through a compromise between accuracy and efficiency.
