Semi-contention based multi-user diversity: a new way to increase throughput of wireless communications. Wireless communications, due to its low initial deployment cost, high scalability and flexibility, will play a key role in providing broadband communications to sparsely populated areas of Australia. To this end, the Australian government announced "Connect Australia" aiming for nationwide broadband communication services, in which wireless communications is an important component.

Wireless communications, due to its low initial deployment cost, high scalability and flexibility, will play a key role in providing broadband communications to sparsely populated areas of Australia. To this end, the Australian government announced "Connect Australia" aiming for nationwide broadband communication services, in which wireless communications is an important component. This project focuses on improving the throughput of wireless communications, especially for rural areas, through the use of a new technology: semi-contention based multi-user diversity. The outcome of this project will help to connect Australian people and to lift the international profile of Australian engineering science in wireless communications.Read moreRead less
Bifurcations of dissipative solitons. Fundamental research on the basic concepts of solitons in dissipative systems and their bifurcations is the next essential step for further progress in the science of optical pulse generators and amplifiers. Australia was the first country in the world to use self-organized ultra-short pulses, called solitons, in a commercially-deployed optical transmission line. This proposed new research will answer the question of how solitons behave at the ultimate limi ....Bifurcations of dissipative solitons.

Australia was the first country in the world to use self-organized ultra-short pulses, called solitons, in a commercially-deployed optical transmission line. This proposed new research will answer the question of how solitons behave at the ultimate limits of optics. New principles of ultra-short pulse generation and amplification, developed in our research, will provide the basis for an unprecedented increase in the capacity of optical transmission and processing of information.Read moreRead less

Dissipative soliton resonances and their applications. Many branches of science and technology, such as precise eye surgery, biological cell machinery, painless dentistry, optical data storage, material micro-machining and laser fusion, rely heavily on high power femtosecond pulse laser oscillators that deliver the necessary power, in a very short time, to nanometer scale targets within a tissue or a material. A further increase in the power of a pulse and a decrease in its duration, combined wi ....Dissipative soliton resonances and their applications. Many branches of science and technology, such as precise eye surgery, biological cell machinery, painless dentistry, optical data storage, material micro-machining and laser fusion, rely heavily on high power femtosecond pulse laser oscillators that deliver the necessary power, in a very short time, to nanometer scale targets within a tissue or a material. A further increase in the power of a pulse and a decrease in its duration, combined with a reduction in complexity and price can be achieved, but this advance depends strongly on the theory of dissipative solitons, and particularly on the idea of soliton resonances. Novel ideas developed within this project will put new productive tools in the hands of doctors, biologists and physicists.Read moreRead less
Design of Quantized Feedback for Robust Control Systems. Most modern machineries and industrial processes are manipulated using advanced control technologies. With the recent advances in information technology, more and more control systems operate over communications networks.

Most modern machineries and industrial processes are manipulated using advanced control technologies. With the recent advances in information technology, more and more control systems operate over communications networks. However, the technologies used in these control systems are seriously lagging behind because they make little assumptions about problems in digital communications. These problems include sampling errors, quantization errors, transmission errors and transmission delays. The proposed research will develop a new control theory to address this issue. Our work will help Australia maintain a leading role in the area of control and give the Australian industry advantages in applying modern technologies in control and automation.Read moreRead less
