| Abstract(in English) | In this paper, we propose an underwater communication that uses visible light LEDs. In underwater communication, much invesitigation has been done using acoustic technology, but the data rate is yet low. On the other hand, as an alternative, optical communication can achieve high data rate. Moreover, light in visible region penetrates water the most. However, other than the absorption of water, absorption and scattering occured by dissovled particles and planktons can degrade the light penetration. Therefore we analyazed the communication performance under water absorption and scattering process based on Mie theory and evaluated the wavelength dependent underwater optical channel. Lastly, we propose a multi-wavelength transmission combined with adaptive PPM modulation to combat the change in turbidity of ocean water. |
