New Pulsar Instrumentation for Gravitation Wave Detection and Understanding the Emission Mechanism. Millisecond pulsar timing currently provides the most sensitive method of detecting long-period gravitational waves which permeate the Universe. Parkes leads the world in the discovery and timing of millisecond pulsars.

Millisecond pulsar timing currently provides the most sensitive method of detecting long-period gravitational waves which permeate the Universe. Parkes leads the world in the discovery and timing of millisecond pulsars. This has motivated the development of three new advanced instruments including a cyrogenic dual-band receiver, a very wide-band correlator and a baseband recorder with an in-built supercomputer. We aim to exploit these new technologies to systematically study the pulsar population. We will establish a timing array which can detect gravitational waves, enable GLAST to identify over 100 gamma-ray pulsars and study the pulsar emission mechanism at sub-microsecond time resolution.

Recently, the capacity of the broadcast channel with multiple antennas is investigated. Various space-time (ST) processing techniques to adapt channel conditions are utilized to increase capacity. Precoding becomes vital to deal with interferers and cooperation problems efficiently. ST codes will be investigated in conjunction with precoding. We aim to investigate channel adaptive ST coding and precoding techniques to achieve the maximum capacity with practical quality of service requirements. Although the capacity is extensively investigated, implementation methods are relatively less investigated. This project is to fill the cap between implementation (ST coding and precoding methods as outcomes) and theory (capacity analysis).Read moreRead less

Model reduction is an important area of study in the analysis and design of dynamical systems. Its objective is to obtain a low-order model given a high-order system model such that the low-order model closely approximates the input-output behaviour of the original high-order system. Although theory and application of model reduction is well developed, there are many unresolved issues such as efficient model reduction techniques for large-scale circuit simulation and communication applications, frequency-weighted model reduction techniques for controller-design applications, and error bounds for the reduction techniques. The project aims to address these issues.Read moreRead less
