Future development of wireless communications networks will require radical improvements over the existing radio transmission and network solutions to support tremendous growth of data traffic in future networks in an energy-efficient manner.

The project Full-Duplex Radios for Local Access (DUPLO) aims at developing new technology and system solutions for future generations of mobile data networks by introducing a new full-duplex radio transmission paradigm, the same carrier frequency is used for transmission and reception at the same time. The approach holds the potential to significantly increase the capacity, and will focus on energy efficient solutions which also enable a more flexible use of the spectrum.

DUPLO will study and develop technical solutions for efficient self-interference cancellation in wireless transceiver to enable usage of full-duplex transmission in different nodes of the wireless communications networks, including access points, devices and relay nodes. Attainable gains of full-duplex transmission and required system level solutions to accommodate the new transmission mode in wireless communications networks will be investigated. The main focus will be in small radio cell operation environment. Novel solutions for antenna, RF and baseband domain self-interference cancellation will be analyzed and developed. The most promising concepts will be implemented in a test hardware circuitry. A proof-of-concept test platform will integrate the developed technical solutions together into functional full-duplex communication system, which can be used in testing and further development of novel solutions.
