Описание: This book treats the problems of single cell resource allocation, multiple cells resource allocation, centralized resource allocation, distributed resource allocation, the case of collaboration between base stations and the case without base station collaboration, in addition to the case of user cooperation and the case without user cooperation.
Описание: This is one of the first books to introduce underwater acoustic networks from the networking and system perspectives, covering the key underwater technologies from the physical to the application layers. It begins with a detailed discussion of underwater communication methods and underwater acoustic channel characteristics.
Описание: Real-time Digital Signal Processing: Implementations and Applications has been completely updated and revised for the 2nd edition and remains the only book on DSP to provide an overview of DSP theory and programming with hands-on experiments using MATLAB, C and the newest fixed-point processors from Texas Instruments (TI). .
Описание: Combines both the DSP principles and real-time implementations and applications, and now updated with the new eZdsp USB Stick, which is very low cost, portable and widely employed at many DSP labs.
Описание: Fuzzy logic is a computational paradigm capable of modelling the own uncertainness of human beings. This wide-ranging book focuses in-depth on the VLSI CMOS implementation and application of programmable analogue Fuzzy Logic Controllers following a mixed-signal philosophy.
Описание: Indoor Wireless Communications: From Theory to Implementation provides an in-depth reference for design engineers, system planners and post graduate students interested in the vastly popular field of indoor wireless communications. It contains wireless applications and services for in-building scenarios and knowledge of key elements in the design and implementation of these systems. Technologies such as Wireless Local Area Networks, Bluetooth, ZigBee, Indoor Optical Communications, WiMAX, UMTS and GSM for indoor environments are fully explained and illustrated with examples. Antennas and propagation issues for in-building scenarios are also discussed, emphasizing models and antenna types specifically developed for indoor communications. An exhaustive survey on indoor wireless communication equipment is also presented, covering all available technologies including antennas, distribution systems, transceivers and base stations.
Описание: This book describes state-of-the-art concepts of cooperative two-way relay technology from theory to practice, from the basics to more advanced theory. The introductory sections of the book illustrate the basics, while the more in-depth theory and analysis allow higher-level students to investigate advanced concepts.
Описание: This book develops for the first time a complete and connected nonlinear theory for the analog Phase-Locked Loop (PLL) which clarifies the obscure points of its complex non-linear behaviour. The book suggests new non-linear models for the PLL components and applies the averaging method to analyse PLL. The book presents the physical interpretation of the PLL operation, locates the difficulties presented by its operation and suggests solutions to overcome these problems. Finally it provides closed form expressions for all the important measures of the PLL and proposes new design criteria.
Описание: Phase-Locked Loops (PLLs) are electronic systems that can be used as a synchronized oscillator, a driver or multiplier of frequency, a modulator or
demodulator and as an amplifier of phase modulated signals. This book updates the methods used in the analysis of PLLs by drawing on the results obtained in the last 40 years. Many
are published for the first time in book form.
Nonlinear and deterministic mathematical models of continuous-time and discrete-time PLLs are considered and their basic
properties are given in the form of theorems with rigorous proofs.The book exhibits very beautiful dynamics, and shows various physical phenomena observed in synchronized oscillators
described by complete (not averaged) equations of PLLs. Specially selected mathematical tools are used - the theory of differential equations on a torus, the phase-plane portraits on a
cyclinder, a perturbation theory (M
lnikov's theorem on heteroclinic trajectories), integral manifolds, iterations of one-dimensional maps of a circle and two-dimensional maps of a cylinder. Using these tools, the properties of
PLLs, in particular the regions of synchronization are described.
Emphasis is on bifurcations of various types of periodic and chaotic oscillations. Strange attractors in the
dynamics of PLLs are considered, such as those discovered by Rossler, Henon, Lorenz, May, Chua and others.
