Influence of electromagnetic emissions from mobile phones on nervous function in the human brain and heart. This research will investigate the influence of mobile phone electromagnetic exposures on the nervous function of the human brain and heart. Brain activity will be monitored by EEG recordings, and heart function will be measured by blood pressure and ECG. As far as possible the methodologies employed will be consistent with previous reported studies in order to allow comparisons, and use ....Influence of electromagnetic emissions from mobile phones on nervous function in the human brain and heart. This research will investigate the influence of mobile phone electromagnetic exposures on the nervous function of the human brain and heart. Brain activity will be monitored by EEG recordings, and heart function will be measured by blood pressure and ECG. As far as possible the methodologies employed will be consistent with previous reported studies in order to allow comparisons, and use standardised quantifiable metrics so that the biological significance of the data can be meaningfully interpreted. The outcomes of this project will address uncertainties in the present data which are of concern to national and international regulatory and health agencies.Read moreRead less
Improved design of hearing protection devices with binaural voice pick-up and hearing loss compensation. Hearing protection is essential to industries operating under extreme noise conditions. However, conventional hearing protection devices such
as earplugs and earmuffs inhibit face-to-face communications. Sensear
has developed and marketed a world-first product that, apart from overcoming the aforesaid limitation, also gives the wearer a perception of his surrounding sound field. This projec ....Improved design of hearing protection devices with binaural voice pick-up and hearing loss compensation. Hearing protection is essential to industries operating under extreme noise conditions. However, conventional hearing protection devices such
as earplugs and earmuffs inhibit face-to-face communications. Sensear
has developed and marketed a world-first product that, apart from overcoming the aforesaid limitation, also gives the wearer a perception of his surrounding sound field. This project seeks to extend Sensear's products to include compensation for people with hearing loss. This will give Sensear a competitive edge in hearing protection products, and enhance Australia's reputation in assistive hearing technology. The project also presents a number of opportunities to provide
industry-focussed research training to PhD students.Read moreRead less
High Bandwidth Efficient Schemes for Portable Multimedia Communications. The introduction of multimedia services for mobile users has resulted in a shortage of satellite spectrum. Spot beam technology is used to provide service in areas of high user density. Adjacent overlapping beams are allocated different frequency bands, however interference from neighbouring beams limits capacity. Multi-User Detection is a technology capable of significantly increasing capacity by frequency re-use in adj ....High Bandwidth Efficient Schemes for Portable Multimedia Communications. The introduction of multimedia services for mobile users has resulted in a shortage of satellite spectrum. Spot beam technology is used to provide service in areas of high user density. Adjacent overlapping beams are allocated different frequency bands, however interference from neighbouring beams limits capacity. Multi-User Detection is a technology capable of significantly increasing capacity by frequency re-use in adjacent spot beams. The aim of this project is to investigate receiver design for multi-user spot-beam channels and develop associated synchronisation and channel estimation methods. The outcome will be efficient communications systems supporting higher user populations, without increasing the bandwidth required.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.
