Visible Light Communications for Smart Manufacturing Environments (Advert Reference: RDF19/EE/MPEE/GHASSEMLOOY)


Project Description

The modern manufacturing is reaching a new level of flexibility, which allows fabrication of personalized products. In manufacturing environments all the robots, machines and tools used are required reconfiguration on regular basis to allow flexibility and efficient use of resources, thus leading to increased productivity. This is achieved by free up the robots and machines by the way of avoiding the use of communication cables and replacing them with wireless communication technologies. In such environments, currently the main wireless technologies used are Z-Wave, Bluetooth Smart, ZigBee, WiFi, and low-power wide-area network, which are all based on using the highly congested and costly radio frequency spectrum. However, there is the attractive alternative technology of optical wireless communications and in particular visible light communications (VLC) (or LiFi), which is license free offering high data rates, high energy efficiency, high security (highly desirable in modern manufacturing) and robustness against interference. The VLC technology uses the light emitting diodes based lighting fixture in order to provide multiple functionalities including illuminations, data communications, indoor positioning (i.e., GPS) and sensing. This research will investigate distributed multiple input multiple output (MIMO) VLC system for indoor positioning and data communications by developing a comprehensive mathematical model and considering the best trade-off between complexity and performance. The project will also involve comprehensive channel modelling considering both dynamic and semi-static conditions as well as the transmitter and receiver characteristics; visible light communications front end design; efficient signalling schemes for distributed MIMO and development of a dedicated testbeds for experimental verification of the proposed solutions in a manufacturing environment. The successful candidate will join OCRG one of the leading research groups in the world with extensive expertise and research activities in the field of Optical Wireless Communications. The applicant should have a good first degree or MSc in communications engineering, optical communications, electrical/electronics engineering, physics, and digital signal processing.

The principal supervisor of this project is Fary Ghassemlooy.
