Service level agreements guaranteeing quality of service have helped your organization to keep old customers and win new ones over. Although it may be easy for the sales department to ink a service level agreement, you have to handle the constant problems of phase fluctuations, jitter, and wander, that threaten the quality of service spelled out in these service level agreements.

This must-have reference on packet switching and signaling offers you an in-depth understanding of the core packet switching architectures, signaling flows, and packet formats, as well as service delivery. It describes in detail the design principles for packet telephone switches and emphasizes the benefits of a distributed architecture and separating bearer and control. Successful carrier-grade deployments of packet telephony entail much more than simply stuffing voice samples into IP packets or ATM cells. They involve deploying multiple protocols, and this book gives you a solid understanding of all protocols used and a clear sense of where individual protocols fit in a packet-based system.

Single- and Multi-carrier Quadrature Amplitude Modulation Principles and Applications for Personal Communications, WLANs and Broadcasting L. Hanzo Department of Electronics and Computer Science, University of Southampton, UK W. Webb Motorola, Arlington Heights, USA formerly at Multiple Access Communications Ltd, Southampton, UK T. Keller Ubinetics, Cambridge Technology Centre, Melbourn, UK formerly at Department of Electronics and Computer Science, University of Southampton, UK Motivated by the rapid evolution of wireless communication systems, this expanded second edition provides an overview of most major single- and multi-carrier Quadrature Amplitude Modulation (QAM) techniques commencing with simple QAM schemes for the uninitiated through to complex, rapidly-evolving areas, such as arrangements for wide-band mobile channels. Targeted at the more advanced reader, the multi-carrier modulation based second half of the book presents a research-orientated outlook using a variety of novel QAM-based arrangements. * Features six new chapters dealing with the complexities of multi-carrier modulation which has found applications ranging from Wireless Local Area Networks (WLAN) to Digital Video Broadcasting (DVB) * Provides a rudimentary introduction for readers requiring a background in the field of modulation and radio wave propagation * Discusses classic QAM transmission issues relevant to Gaussian channels * Examines QAM-based transmissions over mobile radio channels * Incorporates QAM-related orthogonal techniques, considers the spectral efficiency of QAM in cellular frequency re-use structures and presents a QAM-based speech communications system design study * Introduces Orthogonal Frequency Division Multiplexing (OFDM) over both Gaussian and wideband fading channels By providing an all-encompassing self-contained treatment of single- and multi- carrier QAM based communications, a wide range of readers including senior undergraduate and postgraduate students, practising engineers and researchers alike will all find the coverage of this book attractive.

Mit den Fortschritten in der Mikroelektronik wächst auch der Bedarf an VLSI-Realisierungen von digitalen Signalverarbeitungseinheiten. Die zunehmende Komplexität der Signalverarbeitungsverfahren führt insbesondere bei Signalen mit hoher Quellenrate auf Anforderungen, die nur durch spezielle Schaltungsstrukturen erfüllt werden können. Dieses Buch behandelt Schaltungstechniken und Architekturen zur Erzielung hoher Durchsatzraten von Algorithmen der Signalverarbeitung. Neben alternativen Schaltungstechniken zur Realisierung der Basisoperationen, Addition, Multiplikation und Division werden CORDIC-Architekturen zur Implementierung transzendenter Funktionen vorgestellt. Zur Konzeption von Systemen mit Parallelverarbeitung und Pipelining wird ein allgemeines Verfahren zur Abbildung von Signalverarbeitungsalgorithmen auf anwendungsspezifischen Architekturen erläutert. Hierzu werden beispielhaft spezielle Architekturen für Filter, Matrixoperationen und die diskrete Fouriertransformation erörtert. Architekturen programmierbarer digitaler Signalprozessoren sowie beispielhafte zugehörige Implementierungen sind eingeschlossen. Das Buch soll sowohl Studenten und Ingenieure der Elektrotechnik als auch der technischen Informatik mit Architekturkonzepten der digitalen Signalverarbeitung vertraut machen.

Aus den Besprechungen: "Unter den zahlreichen Einführungen in die Wahrscheinlichkeitsrechnung bildet dieses Buch eine erfreuliche Ausnahme. Der Stil einer lebendigen Vorlesung ist über Niederschrift und Übersetzung hinweg erhalten geblieben. In jedes Kapitel wird sehr anschaulich eingeführt. Sinn und Nützlichkeit der mathematischen Formulierungen werden den Lesern nahegebracht. Die wichtigsten Zusammenhänge sind als mathematische Sätze klar formuliert." #FREQUENZ#1
