Communication Theory Lab
Machine-translated · View original
The lab pursues the essence of communication, drawing on even light and noise.
AboutAbout the lab
Going beyond the framework of communication to reach its essence
The Yamazato Lab approaches communication from outside its conventional framework, with the aim of getting at what communication fundamentally is.
The lab works on visible light communication, which uses visible light instead of radio waves, and on underwater optical wireless communication, which sends information through water with blue and green light.
Its research also covers communication that deliberately makes use of noise, and semantic communication that draws on machine learning.
In visible light communication, the lab studies applications in transportation, such as sending data from LED traffic lights to moving vehicles.
Key terms
- Visible light communication
- Communication that sends information by blinking light from LEDs or similar sources too fast for the human eye to see
- Stochastic resonance
- A phenomenon in which, counterintuitively, a system responds better as noise increases
- Semantic communication
- An approach to communication that, rather than sending data as it is, focuses on sending the meaning that is meant to be conveyed

ResearchResearch themes
The lab approaches communication from outside its existing framework, through communication that deliberately uses noise, communication that uses visible light instead of radio waves (visible light communication), and communication that draws on machine learning. In doing so, it aims to get at the essence of communication.
*Illustrative imageVisible light communication from LED traffic lights to vehicles
This research develops visible light communication, which sends information by blinking LED light too fast for the human eye to see, for use in transportation. The lab uses a high-speed camera as the receiver and works on road-to-vehicle visible light communication, which sends data from LED traffic lights to moving vehicles.
*Illustrative imageUnderwater optical wireless communication
This technology sends information through water using blue and green light. It offers higher speed and lower latency than acoustic communication, but is vulnerable to water turbidity and optical axis misalignment. The lab therefore combines communication technology with beam tracking technology to achieve stable optical communication underwater.
*Illustrative imageStochastic resonance communication that uses noise
This research applies stochastic resonance to communication. By deliberately adding noise at the receiver, the lab works toward communication that uses signals so weak that an ordinary receiver cannot even detect them.
