Paper Details

The 71% surface of Earth is covered with water in one form or another, but till date this area is lesselaborated as compared to free space wireless communication in deep space and in air. The underwater communicationis always been subject to improvement and advancements as the medium is subject to changes that is directlyproportional to the natural habitats and Eco system. Due to advance in technology in past decades the underwatercommunication has received the prime importance and dedications, the result of which the Acoustical communicationwhich is communication technology using the sound as media has reached to the peak position, but it is not the supremetechnology though the RF and majority of Electromagnetic spectrum absorbs by water. On the other hand the visiblelight communication has opened the door for the fast, mobile, flexible and application dependent short rangecommunication. The present thesis describes the overall effect of underwater time varied parameters on the beam of lighttransmitted from transmitter to receiver there by enabling the readers and researchers to summarizes the practicalcommunication underwater using free space visible light. Further the recent advance in modulating scheme like CSK andvariable OOK with dimming control, have influence this entitled thesis to implement the mathematical model for theinhibiting such technique at a specific frequency of interest that is subject to least attenuation while propagatingunderwater, thereby providing long range , speed and flicker free and Inter symbol interference free communication. Thethesis is summarized and concluded by the simulating various channel parameters and hardware effect on the overallpower received
