LiFi has been widely shown to be a promising technology for efficient wireless connectivity in underwater environments. This speech will introduce underwater LiFi (U-LiFi) from the signal transmission perspective. Specifically, multi-dimensional signal transmission schemes by exploiting the frequency, polarization and wavelength domain resources in U-LiFi systems will be presented.
