Architecture-based Open Network Management Systems for Next Generation Telecommunications. We aim to develop an open, policy-based architecture for the management of next generation telecommunications networks. It is expected that a comprehensive Open Architecture-based Telecommunications Management Network (AuTuMN) framework could be put in place to manage the network based on centralised policies and roles rather than having to handle individual users and elements.

Plasma layers, waves and fountains: Probing the ionosphere with over-the-horizon radars. The ionised layers of the Earth’s upper atmosphere – the ionosphere - bend radio waves emitted by HF radio communication and radar surveillance systems allowing detection of targets beyond the horizon. This research will provide direct scientific support to this infrastructure including the $1.8B Australian coastal surveillance radars used to locate and track ships and planes in our region and radio communic ....Plasma layers, waves and fountains: Probing the ionosphere with over-the-horizon radars. The ionised layers of the Earth’s upper atmosphere – the ionosphere - bend radio waves emitted by HF radio communication and radar surveillance systems allowing detection of targets beyond the horizon. This research will provide direct scientific support to this infrastructure including the $1.8B Australian coastal surveillance radars used to locate and track ships and planes in our region and radio communication links used by military personnel and civilians living or travelling in Australia’s remote territories. This project will also provide training in areas highly relevant to our partners in government and defense, potentially improve efficiency of scientific and military radars, and thus contribute to improving national security.Read moreRead less
Adaptive Transmitters in Wireless Communication Networks. The mobile Internet requires at least an order of magnitude

Meeting the global demand for mobile and wireless communications depends critically on reliable and high rate data transfer. Unfortunately, communications medium idiosyncrasies pose formidable challenges. Very recently, in combatting this, major breakthroughs have been achieved whereby the use of multiple antennas allows for drastic data-rate increases. These advances use sophisticated Space-Time coding methods, and while they are causing great excitement in terms of their simulation performance, it is not clear how they will perform in practice, or in fact how they are to be realistically implemented. This project will address this issue by building a world-first testbed that implements a high rate wireless communications system using Space-Time and other coding methods.Read moreRead less

Novel multi-channel and nonlinear Bragg grating devices. High capacity and reliable telecommunications links are essential for many aspects of modern life and work. Optical fibres offer essentially unlimited capacity, but their optimal use requires the transmission of multiple wavelength channels simultaneously. This, in turn, requires the development of special-purpose fibre devices for multiplexing and de-multiplexing these channels, as well as for other optical filtering and switching tasks. ....Novel multi-channel and nonlinear Bragg grating devices.

This, in turn, requires the development of special-purpose fibre devices for multiplexing and de-multiplexing these channels, as well as for other optical filtering and switching tasks. Fibre Bragg gratings are central to many of these devices, and the aim of this project is to develop novel designs for linear and nonlinear Bragg grating devices which may significantly widen the current range of their applications.Read moreRead less

New generation telecommunications networks are required to support increasingly demanding services, including interactive multimedia and conferencing. The success of these networks will rely on the users' perception of their quality of experience. The management of these networks will rely on the ability of informed decision making that competes effectively for limited resources in such a highly dynamic environment. This project will design information distribution strategies and smart decision making agents that negotiate a user's quality of experience using market mechanisms. Designs from this project will be trialled and validated in the partner's commercial networks.Read moreRead less
