Optical Communication Theory and Techniques
Since the advent of optical communications, a greattechnological effort has been devoted to the exploitation of the huge bandwidth of optical fibers. Sta- ing from a few Mb/s single channel systems, a fast and constant technological development has led to the actual 10 Gb/s per channel dense wavelength - vision multiplexing (DWDM) systems, with dozens of channels on a single fiber. Transmitters and receivers are now ready for 40 Gb/s, whereas hundreds of channels can be simultaneously amplified by optical amplifiers. Nevertheless, despite such a pace in technological progress, optical c- munications are still in a primitive stage if compared, for instance, to radio communications: the widely...
MIAW 2014
In the contemporary age, the city is increasingly seen as an experiential field. The new transformation processes are asking architects to become more culturally aware and sensitive as well as to read, interpret and implement the system of opportunities offered by the urban scenario. Participants to the Miaw workshop identify spaces in Milan that either have unexpressed potentialities either lost their characters, for several reasons. Leftovers which are marginalized and excluded from everyday life. From the smallest corner in the dense fabric to the large areas on the city borders, the Workshops worked to envision possible strategies of re-forming and revitalizing these dormant places. In a century that is overwhelmed by image, information and dynamism, it seems particularly important for architects and policy makers to recognize and assume the special role of the creative recovery of forgotten spaces.
Photonic Applications for Radio Systems Networks
This hands-on, practical new resource provides optical network designers with basic but necessary information about radio systems air interface and radio access network architecture, protocols, and interfaces, using 5G use cases as relevant example. The book introduces mobile network designers to the transmission modeling techniques for the design of a radio access optical network. The main linear and non-linear propagation effects in optical fiber are covered. The book introduces mobile network designers to the optical technologies used in digital and analog radio access networks, such as optical amplifiers and transmitters, and describes different deployment scenarios, including point-to-p...
Detection Algorithms for Wireless Communications
Wireless channels are becoming more and more important, with the future development of wireless ad-hoc networks and the integration of mobile and satellite communications. To this end, algorithmic detection aspects (involved in the physical layer) will become fundamental in the design of a communication system. This book proposes a unified approach to detection for stochastic channels, with particular attention to wireless channels. The core idea is to show that the three main criteria of sequence detection, symbol detection and graph-based detection, can all be described within a general framework. This implies that a detection algorithm based on one criterion can be extended to the other c...
Optical Fiber Telecommunications
Optical Fiber Telecommunications, Volume Eleven, covers the latest in optical fiber communications and their potential to penetrate and complement other forms of communication, such as wireless access, on-premises networks, interconnects and satellites. This updated edition of this classic, first published in 1979, examines opportunities for future optical fiber technology by presenting the latest advances on key topics, such as 5G wireless access, inter and intra data center communications, THz technologies, secure communications, and free space digital optical links. Topics of note include sections on foundries for widespread user access, designing photonic integrated circuits (PICs), mono...
Optical Networking
This up-to-date collection of research papers from the field of optical network design comprises the proceedings of the 11th Tyrrhenian Workshop on Digital Communications held in Italy, September 1999. Contributions from internationally renowned experts provide the reader with an insight into the design aspects of modern optical networking at the protocol, system and device levels. Subjects are self-contained and reflect the focused views of those who participate in active research in this field. Contributors give their personal opinions and answer questions on the following topics: - Boundaries of the Optical Network Layer in Future Communications Networks. - Management of the Optical Network Layer. - Fiber, Optoelectronic and Integrated-Optic Devices and Components for Switched/Unswitched Optical Networks. - System Technologies in the Networking Scenario. - Switching and Access: Switched WANs, Switched/Unswitched LANs. Expertise and experience combine in this volume to provide a current overview of recent advances in the field. This instructive volume will help readers follow the current research literature and improve their own research.
Unorthodox Ways to Think the City
This book argues that architecture and the city and their processes can be better understood by drawing categories from disciplines that exceed the architectural and urban cultural context. It performs an open intellectual reading that traverses architecture and architectural theory, but also art theory and history, cartography, philosophy, literature and cultural studies, to unfold a series of ‘figures’ that are ambiguously placed between the representation and the construction of space in architecture and the city. The paradigm and philosophy, the island and the city, the map and representation, the model and making and the questioning of form performed by dust, are explored beyond the...
Totem and taboo in architectural imagination
Identify powerful features of the architecture of the present time seeking to illuminate hidden knowledge and processes through a few key concepts. The image: apparently, it seems so essential to understand today’s architecture but which, on closer analysis, turns out instead to be an absence, an unsolved problem, an enigma hidden behind a culture secretly afflicted by iconoclasm. Post-production and montage: so relevant in the avant-garde and now fixed as an indispensable but often hidden creative component. The parody: the hidden but almost always present humor that corrodes the immediate message of architecture and makes it more unstable and, above all, more interesting. Ornament: a component censored by Modernism that today is once again the protagonist in new guises. The relationship with the classic: a secret affair that remains as a founding root of Western architecture.
Optical Modulation
This books aims to present fundamental aspects of optical communication techniques and advanced modulation techniques and extensive applications of optical communications systems and networks employing single-mode optical fibers as the transmission system. New digital techqniues such as chromatic dispersion, polarization mode dispersion, nonlinear phase distortion effects, etc. will be discussed. Practical models for practice and understanding the behavior and dynamics of the devices and systems will be included.
