Signals for networks

In the conventional wireless networking paradigm the physical layer is assumed to apply only to individual links between pairs of devices. This means that signals from other devices in the network must be treated as harmful interference. Increasingly, however, cooperative wireless networks are being developed, in which devices cooperate at the physical layer, allowing the system instead to exploit signals from elsewhere in the network.

In our research we pursue the novel, disruptive paradigm of the “network-aware physical layer”, using techniques like wireless physical-layer network coding (WPNC) to develop networks where all signals are fully exploited to provide significant improvements in end-to-end network performance. Such techniques also lead to new architectures for radio access networks (RAN), and provide new approaches to the “Cloud-RAN” concept, as well as for distributed massive MIMO, greatly reducing front haul load. The techniques are also applicable to the IoT and other machine-type networks.
