Описание: Principles of Mobile Communication, Third Edition, is an authoritative treatment of the fundamentals of mobile communications. This book stresses the fundamentals of physical-layer wireless and mobile communications engineering that are important for the design of any wireless system. This book differs from others in the field by stressing mathematical modeling and analysis. It includes many detailed derivations from first principles, extensive literature references, and provides a level of depth that is necessary for graduate students wishing to pursue research on this topic. The book's focus will benefit students taking formal instruction and practicing engineers who are likely to already have familiarity with the standards and are seeking to increase their knowledge of this important subject.

Описание: The book gives an in-depth description of the key devices of current and next generation fibre optic communication networks. In particular, the book covers devices such as semiconductor lasers, optical amplifiers, modulators, wavelength filters, and detectors but the relevant properties of optical fibres as well. The presentations include the physical principles underlying the various devices, the technologies used for the realization of the different devices, typical performance characteristics and limitations, and development trends towards more advanced components are also illustrated. Thus the scope of the book spans relevant principles, state-of-the-art implementations, the status of current research and expected future components.
Описание: Fiber-optic communication systems have revolutionized our telecommunication infrastructures вЂ“ currently, almost all telephone land-line, cellular, and internet communications must travel via some form of optical fibers. In these transmission systems, neither the phase nor frequency of the optical signal carries information вЂ“ only the intensity of the signal is used. To transmit more information in a single optical carrier, the phase of the optical carrier must be explored.As a result, there is renewed interest in phase-modulated optical communications, mainly in direct-detection DPSK signals for long-haul optical communication systems. When optical amplifiers are used to maintain certain signal level among the fiber link, the system is limited by amplifier noises and fiber nonlinearities. Phase-Modulated Optical Communication Systems surveys this newly popular area, covering the following topics:- The transmitter and receiver for phase-modulated coherent lightwave systems- Method for performance analysis of phase-modulated optical signals- Direct-detection DPSK signal with fiber nonlinearities, degraded by nonlinear phase noise and intrachannel effects- Wavelength-division-multiplexed direct-detection DPSK signals- Multi-level phase-modulated optical signals, such as the four-phase DQPSK signal.Graduate students, professional engineers, and researchers will all benefit from this updated treatment of an important topic in the optical communications field.

Описание: Wireless Optical Communication Systems addresses the problem of designing efficient signalling and provides a link between the areas of communication theory and modem design for amplitude constrained linear optical intensity channel. Topics include historical perspective, channel impairments, amplitude constraints and the characteristics of popular optoelectronic components. A variety of wireless optical channel topologies are presented along with a survey and analysis of present day signalling techniques employed for these channels. The author provides a unifying framework for signalling design which allows the channel constraints to be represented geometrically and permits the use of modem design principles from electrical channels. Modulation schemes are designed using the formalism of lattice codes and a design process for signalling sets is specified. The use of multiple-input/multiple-output (MIMO) wireless optical channels to improve the spectral efficiency of links is explored. The basic spatio-temporal modem design problem is specified and a spatial multiplexing gain is quantified. New spatial discrete multitone modulation is proposed and the unique features are discussed. Based on measurements on an experimental prototype, a channel model is formulated and a realizable spatio-temporal coding scheme is simulated to quantify performance gains. This volume is organized for professional and academic readers engaged in modem design for wireless optical intensity channels. Significant background material is presented on both the properties as well as on fundamental communications principles. Wireless Optical Communication Systems can be used by physicists and experimentalists as an introduction to signalling design as well as communication systems designers.

Описание: An essential textbook to understand the propagation of light in guided optical structures. The first chapters are devoted to vectorial equations and general properties of vectorial modes: theorems of reciprocity, speeds of group and phase, orthonormality and base decomposition of guided modes, dispersions and concept of effective index. Chap 3 covers plane guides with dimension then optical fibers with circular symmetry. The solutions of the fields are given in analytical form for the guides and in purely numerical form for the others. Chap 4 presents modes theory, successively for two layers and multi-layer fibers, then for graded index fibers. Chapter 5 links vectorial modes degenerated into weak guidance and scalar modes LP. In this chapter the lifting of the degeneration of the modes LP by polarization corrections method is also covered. Chapters 6, 7, 8 and 9 treat properties and manufacturing of all-fibre devices: couplings of modes and networks of Bragg integrated into fibres, properties and applications of frayed fibres, splices between fibers and the dividing couplers 2x2 of power, separators mode and wavelengths and special couplers in configuration Mach-Zehnder such as couplers independent the wavelength, those with abrupt response and those to response adapted to the amplifiers to fibers doped to erbium.
