Abstract The metasurface based beam-steering devices with the advantages of large steering angles, arbitrary channels and ultra-compactness have played an important role for data allocation exchange in optical wireless communication. However, current communication systems are mainly on intensity modulation direct detection (IM/DD), which shows a relative lower transmission capacity, received si...

This paper explores the effects of sunlight on using a low-cost off-the-shelf silicon solar panel as an optical wireless communication (OWC) receiver. A receiver circuit structure has been proposed to maximize simultaneous energy harvesting and data performance. An equivalent model for is discussed. By model, varying conditions performance OWC are estimated. Furthermore, experimental setup deve...

This paper presents a preliminary study aimed to optimize the signal characteristics of an optical indoor wireless communication system for telemedicine and mobile user applications. Specifically, detected signals associated with experimental geometries based on line-of-sight (LOS)-pointto-point-optical link and line-of-sight (LOS)-point-to-pointparallel to a surface-optical links are shown. In...

role in information technology, Internet, multimedia communications, forensics, security systems, and handheld applications. Wireless and optical communications have received tremendous interests from both academics and industries over recent years which led to a significant growth of research and development activities in the fields. There are still lots of challenges in the design of an effec...

Free space optical communication provides a very important method for the satellites orbiting around the earth to communicate with each other. Inter-satellite optical wireless communication systems (IsOWC) are one of the important applications of FSO/WSO technology that will be expand in space in the near future. These systems provide a high bandwidth, small size, light weight, low power and lo...

Artificial neural network (ANN) has application in communication engineering in diverse areas such as channel equalization, channel modeling, error control code because of its capability of nonlinear processing, adaptability, and parallel processing. On the other hand, wavelet transform (WT) with both the time and the frequency resolution provides the exact representation of signal in both doma...
