Underwater Wireless Optical Communication with MIMO Spatial Diversity

There is an increasing need for creative solutions as the requirement for reliable underwater communication expands across multiple areas, including defense, industrial applications, and marine research. In order to improve the functionality of wireless optical communication systems submerged, this research investigates the integration of cutting-edge technology, particularly Spatial variety using Multiple Input Multiple Output (MIMO). Enhancing channel responsiveness and communication dependability in difficult underwater conditions is the main goal. Conventional underwater communication techniques, such acoustic communication, have drawbacks like high latency, constrained bandwidth, and noise susceptibility. UWOC uses the special properties of optical transmissions to get over some of these obstacles. In this paper, it is studied that the effectiveness of wireless optical communication devices operating underwater with quadrature amplitude modulation for multiple input and multiple output. There are some difficulties brought on by the underwater environment, including signal attenuation, scattering, and absorption. Water quality and turbidity can also affect how well optical signals work. In order to create communication systems that work, these issues must be resolved. The effects of these difficulties are considered in this analysis. It is obtained that the bit error rate (BER) for both single input and single output and multiple input and multiple output (MIMO) can be obtained by selecting the optimal modulation technique among various options. The findings demonstrate how significantly spatial variety can enhance system performance, particularly in more turbulent channels and coastal water.
