Download or read book Optical Wireless Communications written by Murat Uysal and published by Springer. This book was released on 2016-08-25 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents some of the most important results concerning atmospheric turbulence and some of its effects on the propagation of a light beam. Atmospheric turbulence causes fluctuations in both the intensity and the phase of the beam and still must be understood and modelized for applications in photonics or environmental metrology. The future of free-space optical (FSO) communication through atmospheric turbulence channels is especially of interest and research on high bit-rate communications attracts more and more interest as an alternative to radio links because of bandwidth, spectrum, and security issues. Some of the current solutions for improving FSO communications are presented in this book.

Download or read book Bidirectional Adaptive Optics Architectures for Optical Communication Through Atmospheric Turbulence written by Nivedita Chandrasekaran and published by . This book was released on 2016 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Free-space optical (FSO) classical communication links can provide high data rates vital for successfully serving the world's exponentially growing demand for bandwidth, while FSO quantum key distribution (QKD) links allow information-theoretic rather than computational secure communication between two parties. Unlike fiber-optic classical communication and QKD links, FSO links can do so with minimal up-front investments in infrastructure. Setting aside absorption and scattering losses along the propagation path, optical links with a terrestrial terminal will still experience the deleterious effects of clear-weather turbulence, namely beam spread, beam wander, angle-of-arrival spread, and scintillation, which leads to low end-to-end power transfer from the transmitter to receiver. Decreases in the power transfer result in lower communication rates and may result in no secure-key rate for the loss-sensitive QKD communication protocols. Adaptive optics holds the best promise for mitigating, if not completely compensating for, these turbulence-induced degradations. Nevertheless, despite adaptive optics being a richly developed field, theoretical studies of adaptive optics systems have not fully exploited the reciprocal nature of propagation through atmospheric turbulence. It is known that applying ideal, full-wave adaptive optics at both the transmitter and receiver of a free-space optical link can guarantee scintillation-free power transmission when operation is deep in the near-field power transfer regime. Buoyed by the advent of enabling technologies like scalable Mach-Zehnder interferometer arrays and coherent receiver arrays, this thesis: (1) introduces both a full-wave and phase-only bidirectional adaptive optics (BDAO) protocol; (2) assesses the ergodic performances of FSO classical and QKD communication links utilizing these BDAO systems using both theoretical performance bounds as well as turbulence simulation results; and (3) provides an initial study of the noise and time-dynamics the BDAO protocol can tolerate while still achieving near-optimal classical communication or QKD rates.
