Optimum Multi-rate Filter Bank Design for Speech Enhancement and Communication Systems. Multi-rate signal processing is gaining more and more importance in signal processing applications such as echo cancellation, microphone arrays, speech enhancement and equalisation. This project is aimed at obtaining high performance and high efficiency multi-rate processing designs by developing appropriate problem formulations based on solid mathematical foundations so that powerful optimisation techniques ....Optimum Multi-rate Filter Bank Design for Speech Enhancement and Communication Systems. Multi-rate signal processing is gaining more and more importance in signal processing applications such as echo cancellation, microphone arrays, speech enhancement and equalisation. This project is aimed at obtaining high performance and high efficiency multi-rate processing designs by developing appropriate problem formulations based on solid mathematical foundations so that powerful optimisation techniques can be applied. The developed multi-rate systems will result in low complexity and low power hardware implementations without significant compromise in performance in each application. Size and cost sensitive of communication devices such as personal data assistants, mobile telephones, hands-free devices, and laptops will benefit greatly from the outcome of the project.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
Plasmon mode lasers; smaller, faster, better. High speed Information Technology (IT) communication is using more and more of our global energy. Energy efficiency of IT hardware can be improved by incorporating small, high performance lasers for short distance optical communication. New metallic and plasmonic nano-lasers lasers are indeed smaller and in theory can have performance advantages over current dielectric cavity lasers. This project looks at developing new electrically pumped plasmonic ....Plasmon mode lasers; smaller, faster, better. High speed Information Technology (IT) communication is using more and more of our global energy. Energy efficiency of IT hardware can be improved by incorporating small, high performance lasers for short distance optical communication. New metallic and plasmonic nano-lasers lasers are indeed smaller and in theory can have performance advantages over current dielectric cavity lasers. This project looks at developing new electrically pumped plasmonic lasers with nano scale semiconductors that satisfy requirements for short distance optical communications. Complex systems of these small, fast lasers will also be investigated, with the aim of providing high speed digital processing capabilities exceeding those of electronics.Read moreRead less
Routing shapes of light for the next generation of fibre optic networks. In 2016, the United Nations declared access to the Internet as basic human right. Our communication networks are facing a capacity crunch, which will transform a basic human right for everyone into a privilege for a few. This project aims to avoid a capacity crunch by creating innovative solutions for the next generation of optical fibre communication networks.

In 2016, the United Nations declared access to the Internet as basic human right. Our communication networks are facing a capacity crunch, which will transform a basic human right for everyone into a privilege for a few. This project aims to avoid a capacity crunch by creating innovative solutions for the next generation of optical fibre communication networks. This project stands to generate new knowledge in photonics, optical communication and advanced manufacturing. The expected benefits are new academic collaborations, enhancing Australia’s international standing and economic benefit through commercialisation and training of students for the growing photonics industry in Australia.Read moreRead less
