Abstract
The beamforming based underwater wireless optical communication (UWOC) systems with phase shift keying (PSK) modulation is elucidated in this work. UWOC is a powerful technology which is used for large speed underwater communications. Turbulence is the main mortifying factor of underwater, when light waves are propagating through underwater. For mitigating the turbulence spatial diversity technique is used. The belongings of absorption and scattering are measured here. For calculate the system BER, the sum of log-normal random variables are used. Transmit beamforming is a method to minimize the channel interference. By using transmit beamforming technique the spatial separation between symbols are increased. Study the enactment of UWOC PSK with beamforming and without beamforming. Also compared the enactment of each configuration with existing one. Here, we can analyse that the numerical result of UWOC PSK with beamforming shows a better result than the conventional method, i.e, the BER of UWOC PSK with beamforming is less than that of UWOC OOK.
