The introduction of multimedia services for mobile users has resulted in a shortage of satellite spectrum. Spot beam technology is used to provide service in areas of high user density. Adjacent overlapping beams are allocated different frequency bands, however interference from neighbouring beams limits capacity. Multi-User Detection is a technology capable of significantly increasing capacity by frequency re-use in adjacent spot beams. The aim of this project is to investigate receiver design for multi-user spot-beam channels and develop associated synchronisation and channel estimation methods. The outcome will be efficient communications systems supporting higher user populations, without increasing the bandwidth required.Read moreRead less

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
