In recent years, wireless communications have significantly evolved due to the advanced technology of smartphones;, portable devices; and the rapid growth of Internet of Things, e-Health, and intelligent transportation systems . Moreover, there is anare increasing need fors of emerging intelligent services like positioning and sensing in athe future intelligence society. Recent years have witnessed the growing research interests and activities in the communication and intelligencet services in the optical wireless spectrum, as a complementary technology to more established radio frequency (RF)-based systems, to overcome the spectrum sparsity and increases data rates in crowded locations, due to the limited transmission range and interference. The OWC technology offers advantages such as free license, wide bandwidth, inherent security, no RF electromagnetic interference, and immunity to electromagnetic interference. The attractive applications of the optical spectrum include ultra-violet tactic communication, blue/green underwater communication, visible light positioning, and vehicular communication/sensing in intelligent transportation systems. The present Iissue, as named "Visible Light Communication and Positioning", focuses on visible light communication and visible light positioning, where four papers are on visible light communication and three papers are on visible light positioning. For visible light communication, the published works focus on the devices, the physical-layer techniques, and the system work aspects. Besides VLC, visible light positioning works include fingerprint-based indoor positioning system for multiple reflections, the impact of LED tilt on visible light positioning accuracy, and a mobile optoelectronic tracking system based on feedforward control.

This book demonstrates the research on VLC based indoor localization in four aspects: first, it constructs the concept and model of the system; second, positioning algorithms, as the main issue in indoor localization, are detailed; third, many approaches are proposed to further improve the positioning performance; fourth, challenges will be detailed. Impulse response with multipath reflections are analyzed. Orthogonal frequency division multiplexing (OFDM) is proposed, and positioning performance is largely improved compared to On-off-keying (OOK) modulation. The readers will get a broad view of VLC based indoor localization from the background to the future challenges.

This book focuses on optical wireless communications (OWC), an emerging technology with huge potential for the provision of pervasive and reliable next-generation communications networks. It shows how the development of novel and efficient wireless technologies can contribute to a range of transmission links essential for the heterogeneous networks of the future to support various communications services and traffic patterns with ever-increasing demands for higher data-transfer rates. The book starts with a chapter reviewing the OWC field, which explains different sub-technologies (visible-light, ultraviolet (UV) and infrared (IR) communications) and introduces the spectrum of application areas (indoor, vehicular, terrestrial, underwater, intersatellite, deep space, etc.). This provides readers with the necessary background information to understand the specialist material in the main body of the book, which is in four parts. The first of these deals with propagation modelling and channel characterization of OWC channels at different spectral bands and with different applications. The second starts by providing a unified information-theoretic treatment of OWC and then discusses advanced physical-layer methodologies (including, but not limited to: advanced coding, modulation diversity, cooperation and multi-carrier techniques) and the ultimate limitations imposed by practical constraints. On top of the physical layer come the upper-layer protocols and cross-layer designs that are the subject of the third part of the book. The last part of the book features a chapter-by-chapter assessment of selected OWC applications. Optical Wireless Communications is a valuable reference guide for academic researchers and practitioners concerned with the future development of the world’s communication networks. It succinctly but comprehensively presents the latest advances in the field.

The volume includes a set of selected papers extended and revised from the 2011 International Conference on Mechanical Engineering and Technology, held on London, UK, November 24-25, 2011. Mechanical engineering technology is the application of physical principles and current technological developments to the creation of useful machinery and operation design. Technologies such as solid models may be used as the basis for finite element analysis (FEA) and / or computational fluid dynamics (CFD) of the design. Through the application of computer-aided manufacturing (CAM), the models may also be used directly by software to create "instructions" for the manufacture of objects represented by the models, through computer numerically controlled (CNC) machining or other automated processes, without the need for intermediate drawings. This volume covers the subject areas of mechanical engineering and technology, and also covers interdisciplinary subject areas of computers, communications, control and automation. We hope that researchers, graduate students and other interested readers benefit scientifically from the book and also find it stimulating in the process.

Optical Wireless Communication (OWC) is an enabling technology for sixth-generation (6G) and beyond communication networks. Visible light communication (VLC) is a crucial branch of OWC technology expected to meet 6G communication system requirements. The VLC system can facilitate multiple functionalities simultaneously including illumination, ultra-high data rate communications, positioning such as location and navigation services. In VLC systems, a light-emitting diode (LED) functions as a transmitter. A photodetector or imaging sensor acts as a receiver and the visible light is used as the transmission medium. Researchers have shown a great deal of interest in VLC based positing and localization techniques, as visible light positioning (VLP) systems have shown better localization accuracy than radio frequency (RF) based positioning or global positioning system (GPS). This thesis considers the problem of position estimation accuracy in VLC systems in the presence of signal-dependent shot noise (SDSN). We investigate distance and 3D position estimation approaches in different scenarios, focusing on error estimation performance bounds. Additionally, this work attempts to resolve the synchronization problem found in VLP systems.
