A rapidly growing demand for fast wireless services calls for wideband communication systems with wideband antennas, which are compact, aesthetically appealing and inexpensive, yet have good performance. With novel concepts, this project aims to produce a new class of antennas that deliver impressive performance (bandwidth and gain) while taking up a dramatically reduced area in a way that was impossible before, increasing a figure-of-merit to up to seven times the state-of-the-art. Their planar geometry and simplicity lead to low cost. This is expected to create new knowledge, design methods and examples, prototypes, test results and guidelines required to design, optimise and make these versatile antennas for emerging robust broadband wireless systems.Read moreRead less

Novel Techniques for Uncoordinated Massive Access in the Internet of Things. The IoT (internet of things) is the backbone of intelligent transportation, healthcare, energy and smart home systems. To accommodate the exponentially increasing number of IoT devices, a dramatic paradigm shift towards non-orthogonal uncoordinated (grant-free) massive access is underway, where devices transmit data opportunistically over shared channel resources.

The IoT (internet of things) is the backbone of intelligent transportation, healthcare, energy and smart home systems. To accommodate the exponentially increasing number of IoT devices, a dramatic paradigm shift towards non-orthogonal uncoordinated (grant-free) massive access is underway, where devices transmit data opportunistically over shared channel resources. This project aims to develop new receivers for such uncoordinated massive access, where the receivers will be trained to identify transmitting devices, recover their data, and resolve any collisions. These outcomes are expected to emerge as a game changer in IoT communications, benefiting national and international industry to meet future telecommunications needs for the IoT.Read moreRead less

The Internet of Things (IoT) supports the connectivity of almost everything including powerless simple devices (such as radio frequency identification (RFID) tags), making it an indispensable technology for future industry and business. This project is to develop systematic and cost-effective approaches by leveraging existing cellular networks for the connectivity of simple sensors/devices using mobile data collectors (such as smart phones) so that their information becomes available to IoT applications via cellular systems. For example, products’ information stored in RFID tags or power-limited sensors' data can be provided to logistic or IoT applications, respectively, without building dedicated systems via existing cellular systems.Read moreRead less
Sensing and Communications for Tactical Radio: Mapping the RF Weather. This project investigates sensing, localisation and communication strategies to improve the performance of modern tactical radio networks. Such networks face all of the well-known design challenges of mobile ad-hoc networks (MANETs) but with added complication of a contested and adversarial operating environment.

This project investigates sensing, localisation and communication strategies to improve the performance of modern tactical radio networks. Such networks face all of the well-known design challenges of mobile ad-hoc networks (MANETs) but with added complication of a contested and adversarial operating environment. By exploiting the power of radio nodes to sense the radio spectrum, as well as to communicate over it, a distributed network of nodes can create a detailed picture of the surrounding radio-frequency (RF) environment: the nodes can work together to map the “RF weather”. In this project we will design advanced sensing and localisation methods to accurately map the RF spectrum, and then exploit this map in communication system design.Read moreRead less
