Currently, the modulation performances of underwater wireless optical communication are analyzed in horizontal optical transmission link. However, the methods cannot be used in vertical optical transmission link. In order to solve the problem a model of sea attenuation coefficient is proposed. The model is based on the Gaussian distribution model of chlorophyll concentration and the “seawater s...

The aim of this paper is to highlight the prospects and problems of optical wireless communication for applications in the field of Underwater Wireless Sensor Networks (UWSNs). The necessity of wireless underwater connections, especially in UWSN, has dramatically increased in the last few years for a wide range of applications, from environmental monitoring to surveillance. The problem of wirel...

1,2 Department of Electronics and Communication Engineering, Amity University, Lucknow (India) ABSTRACT Underwater Wireless Optical Communications is an arrivingexplanation to extend the demand for broadband links in oceans and seas. In this paper we examinethe Bit Error Rate (BER)attainment of multiple-input multiple-output of Underwater Wireless Optical Communication system (MIMO-UWOC). By us...

In recent years, there has been a growing interest in the use of single-photon avalanche diode (SPAD) optical wireless communication (OWC). The SPAD operates Geiger mode and can act as photon counting receiver obviating need for transimpedance amplifier. Although provide higher sensitivity compared to traditional linear photodetectors, it suffers from dead-time-induced nonlinearity. To improve ...

Optical intelligent reflecting surfaces (OIRS) have the potential to enhance capacity of next generation optical wireless communication systems by re-configuring propagation environment waves. In this work, a submerged OIRS and planar mirror surface (PMS) are used build up non-line sight (NLOS) underwater (UWOC) system. An NLOS UWOC setup, which makes use total internal reflection (TIR) phenome...
