Enhancing communication networks to achieve broadband data rates is now a national priority. Wireless communications is hugely important, with mobile phones, wireless computers, and wireless Internet access to homes, all rapidly growing areas. This project addresses the fundamental bottleneck of interference between links in wireless networks. Wireless unplugs the user and allows him/her to roam, and to set up ad-hoc networks with other users. This research will thus contribute to Australia's increased productivity. Just as importantly, this project addresses fundamental research; it will increase Australia's knowledge base and provide training for students and researchers in how to think about communications problems.Read moreRead less
Information Capacity of High Data Rate Wireless Networks. Future wireless networks must support huge data rates in order to meet
the escalating demands of emerging Internet applications. Required
capacities far exceed those which can be provided by existing wireless
systems. Space-time coding is one very promising new technique which

the escalating demands of emerging Internet applications. Required
capacities far exceed those which can be provided by existing wireless
systems. Space-time coding is one very promising new technique which
may provide a solution. In spite of the potentials of this technique,
there are many important practical issues that affect the realizable
capacities. We aim to investigate two such issues: the impact of
channel uncertainty at the receiver, and the impact of multiple access
interference. This research will provide new directions for the design
of wireless data networks.

Index coding for multimedia content distribution networks. The project aims to develop new bandwidth-efficient index coding schemes to reduce network congestion. A large portion of the increasing internet traffic is due to video content browsing and distribution. This creates serious strains on the current network infrastructure, which is designed to support conventional data. It is crucial to explore new avenues to reduce the network congestion due to large file downloads. The project aims to t ....Index coding for multimedia content distribution networks. The project aims to develop new bandwidth-efficient index coding schemes to reduce network congestion. A large portion of the increasing internet traffic is due to video content browsing and distribution. This creates serious strains on the current network infrastructure, which is designed to support conventional data. It is crucial to explore new avenues to reduce the network congestion due to large file downloads. The project aims to tackle this problem by exploring new index coding techniques that are robust to failures in wireless and wired network links. Using advanced mathematical tools from algebraic number theory and module theory, the project aims to design optimally bandwidth-efficient index coding schemes that enable timely and reliable content distribution to end users.Read moreRead less
Analysis and classification of malicious code. Malicious software such as viruses and worms directly attacks the security, privacy and integrity of Australian e-commerce, large databases and communication channels. The recent uptake of malicious software by organised crime has made finding effective countermeasures more urgent. Around 80% of the malicious code in circulation is disguised in some way. This significantly increases the difficulty of automated detection and delays analysis. Automate ....Analysis and classification of malicious code. Malicious software such as viruses and worms directly attacks the security, privacy and integrity of Australian e-commerce, large databases and communication channels. The recent uptake of malicious software by organised crime has made finding effective countermeasures more urgent. Around 80% of the malicious code in circulation is disguised in some way. This significantly increases the difficulty of automated detection and delays analysis. Automated classification and de-obfuscation technologies are a precondition to applying more sophisticated detection heuristics. The project will be instrumental in safeguarding Australia by protecting critical infrastructure and defending us from online organised crime and information warfare.Read moreRead less

Information theoretic approaches to optimise genome wide association studies with application to continuous and discrete traits. This project aims to develop new mathematical methods to find genetic associations from new genome-wide studies of colorectal cancer and breast cancer risk factors. If successful, this will result in improved use of expensive genetic data to better predict and understand diseases, conditions and other characteristics for humans, animals and plants.
New modulation techniques for future high-mobility wireless communications. Future wireless networks will support huge amounts of mobile data traffic and numbers of terminals. To provide satisfactory service to emerging mass transportation systems such as self-driving cars, high-speed trains, and drones, it will be critical to incorporate the ability for wireless networks to function in high-mobility environments.
