The Chair

Objective

The objective of the Vodafone Chair Mobile Communications Systems at the TU Dresden is to carry out leading-edge research which adds to the advancement of wireless communications technology, by working on industry relevant problems related to next generation wireless systems. Thorough fundamental research as well as close industry cooperation are key to the success of our projects. Wireless/mobile communications is mainly driven by three branches of industry, namely

with each branch having a different view on problems and solutions. It is highly important that each of these different viewpoints is addressed in the research work, to ensure that the results have practical relevance and significance. The Vodafone Chair therefore welcomes industry contacts and partnerships to help meet this objective.

The chair's current focus lies on physical layer research, with a special emphasis on wireless radio network problems (wireless networks capacity), wireless modems (baseband algorithms), RF imperfections ("Dirty RF"), and IC implementation architectures. Of particular interest are problems and solutions which are found in a tradeoff between these focus areas. Chair projects shall also enable researchers to start-up their own company after obtaining their degree, based on the work performed at the chair.

The chair was founded in September 1994 by an endowment of Mannesmann Mobilfunk GmbH, Düsseldorf, Germany. After the acquisition of Mannesmann Mobilfunk by Vodafone Group Ltd. in 2000, the chair changed its name to Vodafone Chair. We would like to thank Vodafone not only for its continuing commitment, but also for providing valuable technical and business insight during our repeated interactions.

Approach

The goal of research lies in providing solutions for challenges in the design of next generation mobile communications systems. By carrying out high-end research on physical layer systems as well as hardware architectures, the chair closes the gap between baseband algorithms and hardware (RF and IC) implementation issues. Advanced software engineering tools together with highly-developed methodologies are enabling capabilities to realize integrated solutions for our partners.


The topics addressed by the system level group range from network deployment, sectorization and power control, to strategies for efficient coordinated multi-point (CoMP) communication and scheduling. New concepts and algorithms developed in this group will improve spectrum and energy efficiency as well as network capacities for radio transmission.

The algorithms and coding group specializes in study of the impairments of RF-hardware and the corresponding baseband compensation algorithms, as well as novel error correcting coding techniques.

The hardware and tools group focuses on architectures for modem signal processing. Ongoing research comprises heterogeneous multi-processor SoCs, including programming paradigms, load distribution strategies, system interconnect and programmable system components. In addition to this, the design methodology and tool framework dedicated to design, implementation and exploration of low-power, flexible, high-performance SoCs is developed.
