The advantages of CO-OFDM can help meet the challenges of future optical networks that Australia depends upon for its information infrastructure and economic growth. Australia is currently at the forefront of optical OFDM technology, and the continuation of these research activities will further improve Australia's international ICT reputation. Furthermore, in the course of the project, a senior research associate and multiple highly-skilled students will be trained and exposed to techniques and innovations in this exciting field.Read moreRead less
Scalable Robust Video Surveillance over Constrained Networks. Real-time monitoring of large numbers of people is becoming increasingly important for applications such as efficient service delivery and security against both common crime and terrorism. The use of human operators for such tasks is infeasible due to the large amount of data collected. Existing autonomous video surveillance systems are prone to high numbers of false alarms and often require expensive hardware. This proposal seeks ....Scalable Robust Video Surveillance over Constrained Networks. Real-time monitoring of large numbers of people is becoming increasingly important for applications such as efficient service delivery and security against both common crime and terrorism. The use of human operators for such tasks is infeasible due to the large amount of data collected. Existing autonomous video surveillance systems are prone to high numbers of false alarms and often require expensive hardware. This proposal seeks to address both difficulties by using rigorous statistical signal processing methods to optimally fuse information from a network of low-cost cameras.Read moreRead less

Analysis and Design of Multi-objective Optimal Multirate Filter Banks. Multirate filter banks are a fundamental subsystem and play a key role in many applications in information technology, such as digital communications and digital audio and video signal processing. Most of the existing design methods of multirate filter banks are based on idealized operation conditions, so often they do not provide practically desirable performance. This project will develop innovative design methods for multi ....Analysis and Design of Multi-objective Optimal Multirate Filter Banks. Multirate filter banks are a fundamental subsystem and play a key role in many applications in information technology, such as digital communications and digital audio and video signal processing. Most of the existing design methods of multirate filter banks are based on idealized operation conditions, so often they do not provide practically desirable performance. This project will develop innovative design methods for multirate filter banks under the worst operational conditions and multiple conflicting design objectives. The results will fill in the gap between the theoretical design and the practical requirements to provide enhanced performance of systems using multirate filter banks.Read moreRead less

Distributed ultra-fast optical clocks for terabit/s communications. The project aims to enable experiments with full spectrum occupation for transmission over field-deployed optical fibre. Future optical communication systems will have to use the full available spectral bandwidth and advanced multiplexing and modulation to achieve ultimate data capacity over a fibre link. To realistically test such links, experiments must be performed over "real-world" fibre links. By linking three telecoms rese ....Distributed ultra-fast optical clocks for terabit/s communications. The project aims to enable experiments with full spectrum occupation for transmission over field-deployed optical fibre. Future optical communication systems will have to use the full available spectral bandwidth and advanced multiplexing and modulation to achieve ultimate data capacity over a fibre link. To realistically test such links, experiments must be performed over "real-world" fibre links. By linking three telecoms research laboratories, the project will create a close collaboration optical network that enables this research. Anticipated outcomes are the opportunity to conduct research over field-deployed fibre links and to prototype and test communication technology over real-world links, creating a simplified path to commercialisation.Read moreRead less
Low-energy electro-photonics: novel materials, devices and systems. This project aims to develop low-power technologies for programming and tuning photonic integrated circuits (PICs). By replacing thermal tuning, the project will reduce power consumption from watts to milliwatts, which also eliminates the thermal crosstalk that limits the complexity of today's PICs. The expected outcome will be the basis for a generic field-programmable photonic chip, which can be used to rapidly prototype desig ....Low-energy electro-photonics: novel materials, devices and systems. This project aims to develop low-power technologies for programming and tuning photonic integrated circuits (PICs). By replacing thermal tuning, the project will reduce power consumption from watts to milliwatts, which also eliminates the thermal crosstalk that limits the complexity of today's PICs. The expected outcome will be the basis for a generic field-programmable photonic chip, which can be used to rapidly prototype designs for production as full custom chips as part of a new Australian industry capability. The expected benefits will be a faster innovation cycle, greater adoption of photonic technologies, and support of research into, for example, neuromorphic optical processing, and advanced communications and sensing systems.Read moreRead less

Mathematical Foundations of Distributed Radar. Conventional military threats to Australia are large or fast moving objects such as ships and aircraft and conventional radar systems are designed to handle such threats.

Conventional military threats to Australia are large or fast moving objects such as ships and aircraft and conventional radar systems are designed to handle such threats. Recent global political shifts have changed the threats to include objects that are small and slowly moving, such as people, small vehicles and boats. Advances in radar hardware make feasible small, low-powered, devices with inherently reduced performance in comparison to deployed systems. Methods for information integration over a dispersed system of such small devices, design of suitable waveform suites and clever local signal processing algorithms will be developed to achieve the performance improvements the hardware offers, to handle the new threats.Read moreRead less
