Enhancing communication networks to achieve broadband data rates is now a national priority. Wireless communications is hugely important, with mobile phones, wireless computers, and wireless Internet access to homes, all rapidly growing areas. This project addresses the fundamental bottleneck of interference between links in wireless networks. Wireless unplugs the user and allows him/her to roam, and to set up ad-hoc networks with other users. This research will thus contribute to Australia's increased productivity. Just as importantly, this project addresses fundamental research; it will increase Australia's knowledge base and provide training for students and researchers in how to think about communications problems.Read moreRead less

capacities far exceed those which can be provided by existing wireless
systems. Space-time coding is one very promising new technique which
may provide a solution. In spite of the potentials of this technique,
there are many important practical issues that affect the realizable
capacities. We aim to investigate two such issues: the impact of
channel uncertainty at the receiver, and the impact of multiple access
interference. This research will provide new directions for the design
of wireless data networks.

Index coding for multimedia content distribution networks. The project aims to develop new bandwidth-efficient index coding schemes to reduce network congestion. A large portion of the increasing internet traffic is due to video content browsing and distribution. This creates serious strains on the current network infrastructure, which is designed to support conventional data. It is crucial to explore new avenues to reduce the network congestion due to large file downloads. The project aims to t ....Index coding for multimedia content distribution networks. The project aims to develop new bandwidth-efficient index coding schemes to reduce network congestion. A large portion of the increasing internet traffic is due to video content browsing and distribution. This creates serious strains on the current network infrastructure, which is designed to support conventional data. It is crucial to explore new avenues to reduce the network congestion due to large file downloads. The project aims to tackle this problem by exploring new index coding techniques that are robust to failures in wireless and wired network links. Using advanced mathematical tools from algebraic number theory and module theory, the project aims to design optimally bandwidth-efficient index coding schemes that enable timely and reliable content distribution to end users.Read moreRead less

Stochastic Construction of Error Correcting Codes with Application to Digital Communications. Modern society would be unrecognisable without error correcting codes; mobile telephones, storage devices such as DVD's and high speed data communications simply would not exist. Yet most theoretical results on error correcting codes are asymptotic in nature and ignore computational complexity issues, that is, they are not representative of many real life situations.

Modern society would be unrecognisable without error correcting codes; mobile telephones, storage devices such as DVD's and high speed data communications simply would not exist. Yet most theoretical results on error correcting codes are asymptotic in nature and ignore computational complexity issues, that is, they are not representative of many real life situations. By building on recent breakthroughs in statistics and stochastic optimisation, this project will develop algorithms for designing optimised error correcting codes subject to realistic finite data length and computational complexity constraints. Successful outcomes will lead to enhanced data communications and storage, greatly benefiting industry and consumers alike.

The project addresses the holy grail in the area of Reed-Solomon/BCH decoding, namely the derivation of algebraic soft-decision decoding algorithms. These codes are the most frequently used error-correcting block codes and their performance does not fulfill its full potential due to the lack of algebraic soft-decision decoding methods.
