Researchers Tilahun Gutema and Wasiu Popoola from the University of Edinburgh’s Institute for Imaging, Data, and Communications (IDCOM) are breaking new ground in underwater optical wireless communication (UOWC).
The research has several promising real-world applications in understanding and protecting marine ecosystems, enabling secure and fast communication between military submarines, underwater drones and other naval assets, enhancing the monitoring and maintenance of underwater infrastructure for the UK’s oil and gas industry, better results in underwater search and rescue missions, and improving the productivity of fish farms and other aquaculture.
The project aims to overcome the limitations of traditional acoustic communication, which, despite its widespread use, suffers from low data rates and high latency. UOWC offers a promising alternative with its potential for high data rates. However, it faces significant challenges such as photon absorption, scattering, and turbulence in underwater environments. To address these issues, the researchers are exploring the use of a novel waveform design technique. This method encodes data on a subcarrier’s frequency using subcarrier intensity modulation, which is both energy-efficient and resilient to underwater turbulence.
The research indicates that the novel method is a highly promising technique for underwater optical wireless communications. Its energy efficiency and resilience to turbulence make it an ideal choice for enhancing data transmission in underwater environments. This advancement is particularly crucial for applications requiring reliable and high-speed communication, such as environmental monitoring, underwater exploration, and military operations.
Looking ahead, the team plans to implement the novel technique in real-time using a reconfigurable digital signal processing (DSP) board. This step will further validate the technique’s practicality and effectiveness in real-world scenarios, ensuring that it can be deployed in various underwater communication applications.
The team recently presented their work, titled “Waveform Design for Resilient Optical Wireless Communications,” at the Rank Prize Symposium on Optical Wireless Communication in Challenging Environments. This presentation highlighted the potential of the novel technique to significantly enhance underwater communication systems, drawing attention from both academia and industry.
The research is a part of TITAN Lighthouse Project 3: Optical Wireless Networks Integration. Lighthouse Project 3 (LP3) focuses on optical wireless networks integration. By integrating optical wireless technologies into existing communication networks, this research paves the way for faster, more secure, and highly reliable data transmission.
