Research Area Mobile Communications



The research group mobile communications is concerned with the design and performance evaluation of mobile communication networks. Our current research is focused on cellular OFDMA networks, such as IEEE 802.16e WiMAX, 3GPP LTE and LTE-Advanced. A particular interest lies in interference mitigation schemes by intelligent, coordinated resource allocation over multiple cooperating base stations. Further activities comprise adaptive scheduling algorithms, self-organization and the application of advanced coding schemes in wireless networks. Our analysis is not limited to the air interface, but takes a holistic view and includes network architecture aspects and protocol issues.

Our methods include system level simulation and emulation, protocol engineering, optimization, queuing theory and prototypical implementation using software-defined-radio equipment. The simulation tools are based on the IKR Simlib and use further libraries developed at our institute.
