This project aims to develop and validate fundamental theories and techniques for a novel intelligent wireless access paradigm to enhance the efficiency in frequency usage. This innovative approach will be one of the critical enablers for massive device access necessary for future wireless network evolution to support the growing Internet-of-Things. It will enable co-working devices to autonomously sense the local radio frequency landscape, determining how to avoid interference, and exploiting opportunities to intelligently and efficiently access the available radio resources. This will lead to enhanced efficiency in radio resource usage. The project will significantly improve the efficiency of current radio resource utilisation and offer solutions to a challenge of national significance.Read moreRead less

A Signal Simulation Facility for GNSS Receiver Design and Testing. The proposed Facility comprises a Global Navigation Satellite System (GNSS) RF Signal Simulator which allows laboratory testing of new signal tracking and navigation solution algorithms, under different scenarios.

The proposed Facility comprises a Global Navigation Satellite System (GNSS) RF Signal Simulator which allows laboratory testing of new signal tracking and navigation solution algorithms, under different scenarios. Simulation of the operation of current and future GPS satellites, and of the new European GNSS "Galileo", is vital for testing new receiver designs. For example, the Facility could be programmed to generate a GPS satellite signal with user-selectable physical variations in the signal path, including the presence of RF jamming sources, high atmospheric disturbances, diffraction effects and multipath. As many of the signal variations are rare and/or unpredictable, the Signal Simulator is the only means to carry out such tests.Read moreRead less
The development of new techniques for partial discharge monitoring and location in high voltage underground power cables. Increased utilization factors have caused a significant increase in the loading of high voltage distribution cables. This increased loading subjects cable insulation to increased stress which can degrade the insulation, cause cable failure and power loss to consumers. On-line cable insulation monitoring is required and partial discharge monitoring in cables provides a viable ....The development of new techniques for partial discharge monitoring and location in high voltage underground power cables. Increased utilization factors have caused a significant increase in the loading of high voltage distribution cables. This increased loading subjects cable insulation to increased stress which can degrade the insulation, cause cable failure and power loss to consumers. On-line cable insulation monitoring is required and partial discharge monitoring in cables provides a viable technique, but technical problems have prevented its application in on-line operation.
This project will develop techniques for such on-line monitoring. High frequency electrical sensors will be used to reduce interference and improve signal levels. Both a coarse alarm and a higher sensitivity monitor will be developed.

This project aims to discover how a biologically inspired auditory model can be tightly integrated into a state-of-the-art deep learning speech processing framework, to model, design and verify a deep learning based auditory model. Voice-based technologies, ranging from cochlear implants to smart homes, are growing at a rapid pace and speech interfaces are being integrated with all aspects of our lives. However, there is a growing demand to improve these voice-enabled services, making them more secure and less open to cyber-crime attack by unauthorised users. The project is expected to improve techniques for modelling and automatic processing of speech and audio signals, which should provide significant benefits, including improved voice biometrics and cochlear implants.Read moreRead less
