High density small cells with large number of simultaneously connected devices will be controlled by the macro cell in the future 5G wireless standards. In this context, interference management becomes critical in achieving high spectral efficiency. An approach called interference alignment (IA) technique has shown great promise in many theoretical studies. However, the performance improvement brought...
In this paper, a wideband, low antenna correlation and high gain array antennas need to be designed for demanding of Massive MIMO system in the fifth generation mobile communication (5G). Firstly, a dual-polarized dipole antenna unit was designed using Finite element numerical calculation method. The operating frequency range of the dipole is 3.5–5.2GHz. Then a method of open scalable modular was...
Electromagnetic band gap (EBG) structures have great potential in microwave communications. This paper reports a study of defect modes in one dimensional EBG structures. Effects of the size and permittivity of a defect in one dimensional EBG structure on the band gap property were investigated. Samples of EBG structures were fabricated by a cutting and inserting method. Transmission properties of...
The collection of photoplethysmography (PPG) signals from optical based sensor probe has been used extensively for the monitoring of heart rate (HR), respiration rate and oxygen saturation (SpO2). Prior research by the Optical Fibre Sensor Research Group has extended the information provided by PPG based devices from monitoring HR and SpO2 to include total haemoglobin concentration (Hb). Research...
