Optical wireless communicationThe effect of natural turbulence on an underwater wireless optical communication (UWOC) link using the on-off-key (OOK) modulation scheme and a coherent plane wave is analyzed in terms of the signal-to-noise ratio (SNR) and the bit-error-rate (BER). The ...
One promising way for meeting these challenges is to employ multichannel optical wireless communication as part of the data center hybrid communication network. In this paper, we analyze three technologies that could be used in this context: MIMO(Multiple-in-Multipleout), multiplexing through orbital...

In underwater optical wireless communication (UOWC), a channel is characterized by abundant scattering/ absorption effects and optical turbulence. Most previous studies on UOWC have been limited to scattering/ absorption effects. However, experiments in the literature indicate that underwater optical tur...
