Funded Amount: 126000

General Information

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.
