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.

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.

Das satellitengestützte Positionierungssystem GPS wurde ursprünglich für die militärische Navigation konzipiert und entwickelt. Bald wurden aber auch die Anwendungsmöglichkeiten im zivilen Bereich erkannt. Unter anderem zählt GPS heute bereits zu den Standardmethoden der geodätischen Punktbestimmung, wobei Genauigkeiten bis in den Millimeterbereich erzielt werden können. Dieses Buch richtet sich an alle, die eine praxisbezogene Beschreibung von GPS hinsichtlich der Beobachtung und der Auswertung suchen. Nach einer elementaren Einführung in das Prinzip von GPS werden die wichtigsten Aspekte der Beobachtung beginnend von der Planung über die Durchführung bis zur Berechnung der Basisvektoren beschrieben. Das Schwergewicht des Buches liegt in der Auswertung. Im Detail werden die Netzbildung, die Transformation der GPS-Ergebnisse in das lokale geodätische Datum sowie die gemeinsame Ausgleichung von GPS und terrestrischen Messungen behandelt, wobei zahlreiche numerische Beispiele angeführt sind. Im Anhang sind neben den Zahlenwerten für die Parameter der bekanntesten Ellipsoide auch die Formelsysteme für die gebräuchlichsten konformen Abbildungen enthalten.
