Our current key research areas include:

Optical Wireless Communications
Optical wireless communication (OWC) is a form of optical communication in which unguided visible or near-infrared (IR) light is used to transmit data. It is an emerging technology that has been around for the last three decades and is gaining more attention as the demand for capacity continues to increase. OWC is one of the most promising alternative technologies for indoor and outdoor applications. It offers flexible networking solutions that provide cost-effective, highly secure high-speed license-free wireless broadband connectivity for several applications, including voice and data, video and entertainment, enterprise connectivity, disaster recovery, illumination and data communications, surveillance, and many others. In this research area, the group focuses on free-space optical communication, visible light communication, indoor infrared wireless communication, underwater optical wireless communication.

Digital Modulation Techniques
In this area, we study various digital modulation techniques for communication systems. This includes single and multicarrier modulation techniques (such as orthogonal frequency division multiplexing (OFDM), carrier-less amplitude and phase modulation (CAP), subcarrier intensity modulation (SIM), etc …). Channel modelling and impairment mitigation, spatial and temporal diversity techniques are also key areas we focus on in the group.

Optical Fibre Communications
Plastic optical fibres (SI-POF) have become a promising candidate as a medium for short-range indoor networks. With appropriate signal processing techniques, plastic optical fibres can be utilised for a gigabit per second transmission over short-range. To that aspect, the group has demonstrated and works on various nonlinear equalisation techniques to compensate for nonlinear distortions and mitigate intersymbol interference for high-speed communication over SI-POF.
