Strong atmospheric turbulence (disturbance due to rain, fog, haze etc.) is a major problem in optical communication system. In this paper, the performance analysis of an optical communication system with Free Space Optics (FSO), Optical Wireless Communication (OWC) and Single Mode Fiber (SMF) in weak atmospheric turbulence has been analysed. Data stream is transmitted at 20Gbps using different ...

Abstract—Personal optical wireless communication is a promising solution for increasing the available communication bandwidth within a room. This technology can offer, with line of sight and diffuse propagation, very high-speed communication between portable devices. This paper presents a generic line of sight, wide line of sight (LOS/WLOS) propagation model and a diffuse (DIF) propagation mode...

Optical wireless communication has been the subject of much research in recent years because of the increasing interest in laser satellite-ground links and urban optical wireless communication. The major sources of performance degradation have been identified as the spatial, angular, and temporal spread of the propagating beam when the propagation channel is multiscattering, resulting in reduce...

We discuss herein whether an optical wireless communication (OWC) system can be a candidate for post 5G or 6G cellular communication. Almost once per decade, mobile is transformed by significant evolution, with each generation developing distinctive concept technology. Interestingly, similar trends have occurred in OWC systems based on visible light and fidelity (Li-Fi). Unfortunately, currentl...

In this paper, we discuss optical encryption and decryption considering wireless communication channels. In wireless communication systems, the wireless channel causes noise and fading effects of the transmitted information. Optical encryption technique such as double-random-phase encryption (DRPE) is used for encrypting transmitted data. When the encrypted data is transmitted, the information ...

Recently, the importance of underwater wireless optical communication has been grown for applications of underwater observation and sea monitoring systems. This communication technology is expected to play a prominent role in investigating climate changes, prediction of natural disasters, discovery of natural resources, marine biology in lake, sea, and ocean environment. Though acoustic modems ...
