Mobile-to-Mobile Communication Systems (M2M)

All present-day mobile radio systems offer mobility only at one end, namely the user's end, while the service provider's end is fixed. This is in contrast to several emerging wireless communication systems, where mobile users can directly communicate with each other. Such systems form a new family of communication systems called mobile-to-mobile communication systems. The driving factor behind mobile-to-mobile communications is the consumer demand for a higher quality of service (QoS), new applications, a nd increased mobility support. Potential applications of mobile-to-mobile communications can be found, e.g., in ad hoc networks and relay based cellular networks in both commercial and military areas. This project focuses on transmission techniques for m obile-to-mobile communication systems. The performance of the developed transmission schemes will be studied under realistic propagation conditions. Recent investigations have shown that the statistical properties of typical mobile-to-mobile channels are quite different from those of classical mobile radio channels, which can result in considerably degraded error performance. Within this project, intensive research will be done in the physical layer with emphasis on the modelling of realistic mobile-to- mobile fading channels, channel coding techniques, channel estimation methods, and signal constellation design schemes for mobile-to-mobile systems. The project proposal is organized in three work packages. The M2M project brings together two leading res earchers in Norway and 11 national and international distinguished partners from industry and other research institutes. In addition, it is planned to supervise 3 Ph.D. students and to do research with 1 postdoc research fellow.
