University of Liverpool
The University of Liverpool was founded in 1881 “For advancement of learning and ennoblement of life” and is recognised for high-quality teaching, research and international collaborations.
The university’s Department of Electrical Engineering and Electronics developed a chromatic sensor for the project. The sensor is used in home care to provide alerts to carers if there is an unusual event (e.g. a fall, seizure, intrusion etc.) The system detects patterns of behaviour that are precursors to age or health related problems, allowing carers to intervene before situations deteriorate and medical intervention becomes necessary. The chromatic sensor units are placed on the ceiling and look similar to conventional smoke detectors. The 5G connection allows high speed data transmissions that are critical for time-sensitive alerts. The sensor technologies are cost effective and passively monitor the living environment whilst maintaining privacy.
The university also produced an environmentally friendly wireless communication trial to show the reduced use of power in 5G over 4G systems and innovative high-performance channel equalisation techniques to combat signal distortion during propagation due to multipath effects. This system can be used to test different equalisation approaches and to validate receiver structures. A paper entitled ‘PA-Efficiency-Aware Hybrid PAPR Reduction for F-OFDM Systems with ICA Based Blind Equalization’ was presented at the IEEE Wireless Communications and Networking Conference 2019.
