Congratulations on taking your first steps toward a Research Degree with Coventry’s Faculty of Engineering, Environment and Computing. As an ambitious and innovative University, we’re investing an initial £100m into our new research strategy, ‘Excellence with Impact’. Through original approaches from world-leading experts, we’re aiming for our research to make a tangible difference to the way we live. As a research student you are an integral part of Coventry’s lively and diverse research community and contribute to our reputation for excellence. With our exceptional facilities and superb support mechanisms you are afforded every opportunity for academic success.
The rapid evolution of computing, consumer electronics, mobile communications and internet of things (IoT) have led to an unprecedented increase in end-user data. Due to the limited available spectrum in radio frequency (RF), there will soon be ‘a RF spectrum crisis’. In order to meet the high-speed communication demands, the future generations of networks must support the co-existence and cooperation of different wireless technologies (RF, millimetre wave, and optical wave). Visible light communications (VLC) systems are widely expected to play a key part in the future generation of connectivity (5G) due to the availability of THz of licence-free spectrum.
In order to improve overcome limited bandwidth of white light emitting diodes (LED), a concept of spatial multiple input multiple output (MIMO) system and wavelength division multiplexing (WDM) have been studied for VLC system. This study focuses on a feasibility of combining spatial and wavelength division multiplexing for multidimensional modulation/multiplexing for VLC system. This project focuses on the study and development of a hybrid WDM-MIMO VLC system. A novel efficient demultiplexing technique will be developed to make the system suitable for deployment in intelligent transport.
About the Centre/Department
Our research in Mobility & Transport works across our faculties and focuses on the design and engineering of future transport systems, including the growing influence of the internet and connectivity. The focus is on inclusive, sustainable and safe transport integrating the strongest research elements in design and engineering. Future transport systems have a number of high level aims including ambitions to totally eliminate road fatalities, to eliminate congestion, to provide users with seamless integrated and connected transport systems, to eliminate emissions and to develop vehicles and systems that use lightweight, efficient and recycled materials.
Successful applicants will have:
- A minimum of a 2:1 first degree in a relevant discipline/subject area with a minimum 60% mark in the Project element or equivalent with a minimum 60% overall module average, or
- A Masters Degree in a relevant subject area will be considered as an equivalent. The Masters must have been attained with overall marks at merit level (60%). In addition, the dissertation or equivalent element in the Masters must also have been attained with a mark at merit level (60%).
- The potential to engage in innovative research and to complete the PhD within a prescribed period of study
- Language proficiency (IELTS overall minimum score of 7.0 with a minimum of 6.5 in each component).
- Background on communication system and digital signal processing
- Enthusiasm and aptitude for both practical and theoretical activities;
- Ability to work with others in a team
