Recent experience of Internet service providers has seen a booming market demand for live Internet broadcasting services. Live broadcasting of high-profile events, such as the Live Earth concerts in July 2007 by MSN, has drawn a global audience of the order of millions of viewers across the Internet. The technology developed in this project will drastically reduce Internet bandwidth consumption for provisioning such large-scale Internet broadcasting services while meeting user satisfaction with guaranteed Quality of Service. It is crucial for Australia to invest in this frontier technology since Australian service providers rely on expensive Internet infrastructure to communicate with major data hubs in other continents.Read moreRead less
Adaptive Multi-user Detectors for Mobile Space-Time Communications Systems over Time Variable Fading Channels. High capacity wire-line internet access (~ 1 Mbit/s) is available through existing telephone lines or through the cable TV infrastructure. The need to have the same quality wireless and mobile internet access is becoming evident. The full deployment of the mobile internet might be delayed due to the low capacity of existing cellular mobile communications systems.
