Project working title 

Dynamic Single Frequency Networks
- cooperative diversity with application to wireless adhoc networks, soft cellular neworks, as and IP over DVB.

Summary of the Research area

The topic of my research is dynamic Radio Resource Management (RRM) schemes for packet based wireless communication systems.  In 1998 I suggested a concept which I call Dynamic Single Frequency Networks (DSFN). Since my Ph.D. studies are kind of delayed, my publications have been cited by several to me unknown authors. The concept implies that several transmitters send the same signal simultaneously to receivers in an exposed position.  This is combined with channel adaptive packet scheduling schemes. The concept can be described as a form of cooperative transmitter macro diversity, that can be applied to any wireless network using the  Orthogonal Frequency Division Multiplex (OFDM) modulation scheme, or other frequency domain equalization (FDE) schemes.


One application I have in mind is improved performance in wireless adhoc networks, for example sensor networks or future UWB and wireless USB systems. Another is IP multicast and unicast services over Terrestrial Digital Video Broadcasting (DVB-T) system, which is utilized as a broadband downlink, supplemented by some narrowband interaction channel. This can be used for interactive services such as localized datacasting services and efficient TV transmission using IP multicasting. The schemes are evaluated regarding system spectral efficiency, fairness, computational complexity and energy consumption. The research method is computer simulations.

Focus and demarcation of the thesis

In the thesis, only non-realtime delay-insensitive best-effort IP traffic without QoS reservation is considerd, only one frequency channel, no power control, only omni-directional antennas, no static cell planning issues, and only one system of centrally controlled transmitters without external interferers.
