A phase modulation-based ultrasonic communication system using Variable Structure Control (2010)
Presentation / Conference Contribution
Ma, S., Wilkinson, A. J., & Paulson, K. S. A phase modulation-based ultrasonic communication system using Variable Structure Control. Presented at 2010 IEEE 12th International Conference on Communication Technology

Narrow bandwidth transducers used in existing ultrasonic data communication systems are known to be devices with a high Q resonant response and low coupling to both the electrical drive and acoustic output interfaces. These features limit the speed o... Read More about A phase modulation-based ultrasonic communication system using Variable Structure Control.

Trends in the incidence of rain rates associated with outages on fixed links operating above 10 GHz in the southern United Kingdom (2010)
