Australia has one of the largest exclusive economic zones in the world, and it is vitally important for Australia to understand and benefit from the oceans. This project will give new perspectives in developing underwater acoustic communications that are important for marine industries and scientific research in areas such as the exploration and exploitation of offshore oil and gas, and ocean environment and climate monitoring. This project will lift the international profile of Australia in underwater acoustic communications research and, through the training of early career researchers and PhD students, this project will also develop a skills base for Australia in underwater acoustic communications.Read moreRead less
Adaptive Modulation For OFDM Signals. The sub band Signal To Noise Ratio in an OFDM communications channel varies by as much as 30 dB. In order to optimise the bandwidth efficiency of OFDM signalling it is desirable to adapt the chosen modulation technique such as M-ary QAM to the SNR available in sub bands. In this way high quality channels transmit the highest bit rates, whilst low quality channels accommodate the lowest bit rates. The net result is that the capacity of the communications link ....Adaptive Modulation For OFDM Signals.

In this way high quality channels transmit the highest bit rates, whilst low quality channels accommodate the lowest bit rates. The net result is that the capacity of the communications link does not have to be limited by designing for worst case conditions.Read moreRead less
Optimal Waveform Design and Compensation Techniques for Non Linear Communication Channels. Distortion effects in satellite amplifiers have a serious impact upon communication system performance, for example, by increasing the error rates.
The research study we are proposing involves analysing these distortion causing non linear effects and designing techniques to compensate for them. Although we are initially interested in the nonlinear satellite channel, we intend the results to be extended t ....Optimal Waveform Design and Compensation Techniques for Non Linear Communication Channels. Distortion effects in satellite amplifiers have a serious impact upon communication system performance, for example, by increasing the error rates.
The research study we are proposing involves analysing these distortion causing non linear effects and designing techniques to compensate for them. Although we are initially interested in the nonlinear satellite channel, we intend the results to be extended to other difficult nonlinear channels such as will be present in future 3G and 4G mobile communication systems.
The proposed research will place Australia at the forefront of cutting edge Information Technology and Communications research.
