Blind separation of mutually correlated sources. This project is aimed at developing novel techniques for blind separation of mutually correlated sources. The expected outcomes will significantly advance the theory of blind source separation and improve the performance of important practical systems, such as densely deployed sensor networks and wireless video surveillance systems.
Analysis of Polynomial Phase Signals with Missing Observations. Many non-stationary signals in radar, physics and communications can be modelled as polynomial phase signals. These signals are often incomplete due to missing observations from intermittent sensor failures, outliers, receiver errors, periodic interference and inaccessibility of data. The aim of this project is to develop robust and computationally efficient methods for recovering such signals from small data sets when there is a la ....Analysis of Polynomial Phase Signals with Missing Observations. Many non-stationary signals in radar, physics and communications can be modelled as polynomial phase signals. These signals are often incomplete due to missing observations from intermittent sensor failures, outliers, receiver errors, periodic interference and inaccessibility of data. The aim of this project is to develop robust and computationally efficient methods for recovering such signals from small data sets when there is a large proportion of missing observations. This will contribute to a conceptual advancement in the field of signal processing and will provide new methods for use in applications such as radar, astrophysics, seismology, vibration analysis and communications.Read moreRead less

This project will detect and measure the signature of the first ionising sources in the early Universe. It uses a unique intersection of information theory and analysis methodology to design and implement a method of extracting the faint neutral hydrogen signal of reionisation from complex datasets. The hydrogen structure around these first light sources will be measured using data from the Murchison Widefield Array telescope in Western Australia, revealing the signature of reionisation for the first time. Measurement of this signal constrains our understanding of the large-scale evolution of the Universe, defines properties of the first generation of stars and galaxies, and expands our understanding of the full history of the Universe.Read moreRead less

This project seeks to measure a radio signal for the first time, using the Murchison Widefield Array telescope and a novel technique involving the Moon, to learn what luminous objects dominated the early Universe. There is an entire period in the early Universe that remains unobserved because familiar objects such as stars and galaxies have yet to form. One of the few observables from this period, and the time directly following it, is the radio signal emitted by neutral hydrogen atoms. Innovative analysis techniques may be developed and new training pathways for astronomers should be initiated. The Project aims to raise Australia’s scientific profile and engage the public, promoting astronomy by making results accessible and using the Moon as a familiar foundation.Read moreRead less
