Interference as a source of green signal power in cognitive relay assisted co-existing MIMO wireless transmissions

This work presents a break-through in the state-of-the-art field of cognitive radio, where spectrum-efficient transmission is achieved by allowing secondary communication links to access frequency resources when these are under-utilized by the licensed operators. By optimizing the licenced-secondary links’ cross-interference, the proposed low-complexity transmitter-based techniques demonstrate a doubling of the transmission rates through the licensed spectrum. This work is part of an international collaboration within the 2.3M€ EU FP7 FET project 'CROWN', with world-leading partners (e.g. TU Dresden, EURECOM and INTEL), and has led to further collaboration with these groups on cognitive radio research.
