It is a breakthrough that has important ramifications for spectral efficiency by potentially doubling the capacity of wireless systems. This could also allow unrestricted international roaming in LTE phones, as well as being the preferred choice for operators when upgrading to 5G networks.
When it comes to duplexing for devices such as smartphones and tablets, self-interference cancelling technology needs to meet the rigorous low cost requirements of handset applications. Leo Laughlin, a PhD student at the University of Bristol’s EPSRC Centre for Doctoral Training in Communications and opening speaker at the event, will present a prototype of the full duplex transceiver with electrical balance duplexing that allows transmission and reception from a single antenna.
The architecture was designed and built by Laughlin along with MSc student Chunqing Zhang, supervisors Professor Mark Beach and Dr Kevin Morris from the University’s Communication Systems and Networks research group, and CW Radio SIG Champion, Professor John Haine of u-blox.
