Efficient signal processing using short word-length techniques. It is expected that the research will lead to significant reductions in cost and computational overheads for signal processing systems in general. These cost/speed enhancements have implications for radar, communications, audio, speech, video, aerospace, defence and biomedical engineering.

These cost/speed enhancements have implications for radar, communications, audio, speech, video, aerospace, defence and biomedical engineering. In the last few decades, developments in enhancing the speed of processing signals has been clearly seen to impinge greatly on the lives of all citizens and so positive outcomes from the research can be expected to translate into increased quality of life for the whole country.Read moreRead less
Stochastic Construction of Error Correcting Codes with Application to Digital Communications. Modern society would be unrecognisable without error correcting codes; mobile telephones, storage devices such as DVD's and high speed data communications simply would not exist. Yet most theoretical results on error correcting codes are asymptotic in nature and ignore computational complexity issues, that is, they are not representative of many real life situations. By building on recent breakthrough ....Stochastic Construction of Error Correcting Codes with Application to Digital Communications. Modern society would be unrecognisable without error correcting codes; mobile telephones, storage devices such as DVD's and high speed data communications simply would not exist. Yet most theoretical results on error correcting codes are asymptotic in nature and ignore computational complexity issues, that is, they are not representative of many real life situations. By building on recent breakthroughs in statistics and stochastic optimisation, this project will develop algorithms for designing optimised error correcting codes subject to realistic finite data length and computational complexity constraints. Successful outcomes will lead to enhanced data communications and storage, greatly benefiting industry and consumers alike.

Adaptive Multi-user Detectors for Mobile Space-Time Communications Systems over Time Variable Fading Channels. High capacity wire-line internet access (~ 1 Mbit/s) is available through existing telephone lines or through the cable TV infrastructure. The need to have the same quality wireless and mobile internet access is becoming evident. The full deployment of the mobile internet might be delayed due to the low capacity of existing cellular mobile communications systems. This research project w ....Adaptive Multi-user Detectors for Mobile Space-Time Communications Systems over Time Variable Fading Channels. High capacity wire-line internet access (~ 1 Mbit/s) is available through existing telephone lines or through the cable TV infrastructure. The need to have the same quality wireless and mobile internet access is becoming evident. The full deployment of the mobile internet might be delayed due to the low capacity of existing cellular mobile communications systems. This research project will contribute to the understanding of fundamental capacity limitations of the mobile communications concept over communication channels that vary with time. The outcomes of the project will suggest possible solutions to the capacity limitations.Read moreRead less
Adaptive Transmitters in Wireless Communication Networks. The mobile Internet requires at least an order of magnitude

The project addresses optimum protocols for the mobile channel resource allocation in conjunction to the optimum transmitter-receiver design.Read moreRead less
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

The provision of broadband services is a high priority for the Australian government as evidenced by the various initiatives around Australia. The merging of backbone infrastructures for access environment will overcome unnecessary cost of maintaining and upgrading two separate networks for wired and wireless applications. The merged infrastructure will potentially provide inexpensive and cost-effective solutions for truly broadband services with a choice of wired or wireless connectivity to customers and will remove the rural-urban broadband divide that has been challenging Australia. The outcomes of this project can lead to new business ventures and will further strengthen the telecommunication industry.Read moreRead less
