Iterative subspace expansions for space-time adaptive wireless communications, radar and sonar. This project addresses the fundamental challenge of high receiver complexity for bandwidth-efficient, high data-rate wireless communications, radar and sonar. We do this by designing the signal transmissions so that smart receivers can detect the signals in "warp speed". We expect these results to have an immediate impact on the design of next generation communications technologies.

Modern telecommunication systems are increasingly built on principles of iteration and feedback. By contributing to the knowledge base of iterative telecommunication systems, this project addresses important fundamental problems in the area of telecommunications. The Federal Government has clearly indicated that it recognises the importance that information and communications technology (ICT) plays in the economic and social fabric of Australia, through the recent Innovation Action Plan, Backing Australia's Ability. These technologies are key drivers of the information economy, the spawning of new businesses, the transformation of established industries, the opening up of new export markets, and the creation of new jobs.Read moreRead less
Space-Time Block Codes using Orthogonal, Amicable, and General Designs. Space-time coding for multiple transmit and multiple receive antennas is the enabling technology for future wireless communication systems. Multiple antennas provide independent transmission paths resulting in an increased channel capacity without requiring costly additional bandwidth.

The currently known codes are base ....Space-Time Block Codes using Orthogonal, Amicable, and General Designs. Space-time coding for multiple transmit and multiple receive antennas is the enabling technology for future wireless communication systems. Multiple antennas provide independent transmission paths resulting in an increased channel capacity without requiring costly additional bandwidth. Space-time block codes lead to the simplest receiver structures and thus to the most economical solutions. The currently known codes are based on the work of one of the CIs, but so far only a small part of that work has been utilised. We aim to fully exploit the potential of this theory and move the performance of wireless systems towards their theoretical limits.Read moreRead less

Multicast communication over lossy networks is becoming the basic for a growing number of aplications. It is therefore critical to provide sound security mechanisms for multicast communication. Yet, existing security protocols for multicast offer only partial solutions. This project is concerned with two major security problems of multicast communications: authentication and secrecy. The goal of this project is to: (1) develop a framework for analysis and evaluation of security services for multicast communication; (2) design efficient algorithms and protocols for securing emerging applications that are multicast-based and/or stream-oriented.
