Abstrakti

This paper highlights recent contributions on the inband full-duplex (IBFD) technology by providing an overview of the related research carried out at Tampere University of Technology, Finland, thus far. In particular, we consider the challenges caused by the own transmitter, which is now a powerful source of self-interference, while also discussing a potential system-level application of the IBFD technology. The former issue is analyzed by presenting advanced signal models for canceling the SI in the digital domain of the receiver. The signal models are derived such that they take into account the most significant analog impairments. As for the system-level application, we propose a self-backhauling IBFD-capable access node that can serve users and backhaul data using the same frequency resources at the same time. This reduces transmit power consumption over the reference scheme that relies on half-duplex operation. Altogether, the findings reported here and in the first author's dissertation demonstrate that the IBFD technology can significantly enhance the spectrum usage of the future wireless networks.
