'Broadband to the Bush' is a national priority - more than 1.6 million homes, small businesses and not-for-profit organizations in rural, regional, and remote Australia are set to benefit from broadband access to phone networks and the internet. The immediate challenges lie in overcoming poor download speeds and area coverage, as well as expensive access. This research will deliver cost and power-efficient receiver architectures to provide end-user utility, and will train postgraduate researchers across traditional discipline boundaries in mathematics and engineering. The project represents an important contribution to frontier technologies in information and communications technology for building and transforming Australian industries.Read moreRead less
Adaptive Modulation For OFDM Signals. The sub band Signal To Noise Ratio in an OFDM communications channel varies by as much as 30 dB. In order to optimise the bandwidth efficiency of OFDM signalling it is desirable to adapt the chosen modulation technique such as M-ary QAM to the SNR available in sub bands. In this way high quality channels transmit the highest bit rates, whilst low quality channels accommodate the lowest bit rates. The net result is that the capacity of the communications link ....Adaptive Modulation For OFDM Signals.

Distortion effects in satellite amplifiers have a serious impact upon communication system performance, for example, by increasing the error rates.
The research study we are proposing involves analysing these distortion causing non linear effects and designing techniques to compensate for them. Although we are initially interested in the nonlinear satellite channel, we intend the results to be extended to other difficult nonlinear channels such as will be present in future 3G and 4G mobile communication systems.
The proposed research will place Australia at the forefront of cutting edge Information Technology and Communications research.

Satellite Data Communications for Remote Sensing and Broadband Connectivity. The remote, distributed location of many of Australia's primary industries preclude the use of consumer-oriented terrestrial wireless broadband services. In many instances, satellite communications provides the only feasible means of connectivity for telemetry, supervisory control and data acquisition, tracking and fleet management. Meteorology, remote sensing, irrigation, mining, oil and gas exploration, and fisheries ....Satellite Data Communications for Remote Sensing and Broadband Connectivity. The remote, distributed location of many of Australia's primary industries preclude the use of consumer-oriented terrestrial wireless broadband services. In many instances, satellite communications provides the only feasible means of connectivity for telemetry, supervisory control and data acquisition, tracking and fleet management. Meteorology, remote sensing, irrigation, mining, oil and gas exploration, and fisheries are just a few examples of high-value applications of particular significance to Australia. This project will develop bandwidth efficient satellite communications technologies that greatly reduce cost and pave the way toward new market opportunities for broadband access and telemetry applications.

Delivering guaranteed quality of service over IP networks. The next revolution in the Internet will be to offer end-to-end Quality of Service (QoS) guarantees, in the form of maximum delay, delay variation and probability of packet loss, or minimum throughput. There are no existing techniques capable of delivering end-to-end QoS guarantees. This project will develop credit-based controls, instead of the usual rate-based controls, that can deliver these required QoS guarantees. These QoS guarante ....Delivering guaranteed quality of service over IP networks. The next revolution in the Internet will be to offer end-to-end Quality of Service (QoS) guarantees, in the form of maximum delay, delay variation and probability of packet loss, or minimum throughput. There are no existing techniques capable of delivering end-to-end QoS guarantees. This project will develop credit-based controls, instead of the usual rate-based controls, that can deliver these required QoS guarantees. These QoS guarantees will enable the development and deployment of entirely new services on the Internet. This project will give Australian industry the opportunity to create the next generation Internet. Therefore this project represents a Frontier Technology.Read moreRead less

Precision clocks are a key enabler for many important technologies including navigation, radar, distributed computing and communications. Unfortunately, the very best clocks are currently bulky and very expensive. This project will take Australia’s multi-award winning sapphire clock technology and transform it so that its unmatched performance is available from a unit with an order of magnitude smaller size, power consumption and cost. This transformation will be driven on the back of a patented revolutionary step that allows operation of the sapphire clock at higher cryogenic temperatures. The new clock will have a wider range of applications delivering more computational power, higher bandwidth transmissions and better radar. Read moreRead less
