The aim of the project is to develop key technologies and novel methods to full-duplex based systems. Both equipment design and systems design aspects are covered. The equipment design perspective of the project improves the current state-of-the-art of the full-duplex transceiver technologies and at the same time increases the understanding of the fundamental degradations caused by the self-interference. In addition, the full-duplex operation changes the fundamental paradigm of separating transmission and reception in time or frequency. This necessitates the development of new system and network concepts and protocols. The technological targets of the project can be divided into more specific objectives presented below.


  • Objective 1: Identify and model systems and networks where full-duplex approach is beneficial.
  • Objective 2: Develop efficient analogue RF and digital baseband self-interference cancellation solutions, transceiver architectures, and circuits including antennas for full-duplex operation and find the attainable performance limits.
  • Objective 3: Develop protocols and networks level solutions for full-duplex networks.
  • Objective 4: Proof-of-concept of full-duplex transceivers and systems.


The objectives of the DUPLO project are directed towards objective ICT-2011.1.1 Future Networks. In particular the project objectives are directly contributing to the target outcomes of enabling technologies for flexible spectrum usage for mobile broadband and novel radio network topologies under the Wireless and mobile broadband systems.


Additionally, DUPLO project is within RAS cluster which comprises a portfolio of more than 20 research projects participating in the 7th Framework Program (Objective 1.1 - Future Networks) and investigates Radio Access and Spectrum aspects of future wireless networks.
