This book introduces the Vienna Simulator Suite for 3rd-Generation Partnership Project (3GPP)-compatible Long Term Evolution-Advanced (LTE-A) simulators and presents applications to demonstrate their uses for describing, designing, and optimizing wireless cellular LTE-A networks. Part One addresses LTE and LTE-A link level techniques. As there has been high demand for the downlink (DL) simulator, it constitutes the central focus of the majority of the chapters. This part of the book reports on relevant highlights, including single-user (SU), multi-user (MU) and single-input-single-output (SISO) as well as multiple-input-multiple-output (MIMO) transmissions. Furthermore, it summarizes the optimal pilot pattern for high-speed communications as well as different synchronization issues. One chapter is devoted to experiments that show how the link level simulator can provide input to a testbed. This section also uses measurements to present and validate fundamental results on orthogonal frequency division multiplexing (OFDM) transmissions that are not limited to LTE-A. One chapter exclusively deals with the newest tool, the uplink (UL) link level simulator, and presents cutting-edge results. In turn, Part Two focuses on system-level simulations. From early on, system-level simulations have been in high demand, as people are naturally seeking answers when scenarios with numerous base stations and hundreds of users are investigated. This part not only explains how mathematical abstraction can be employed to speed up simulations by several hundred times without sacrificing precision, but also illustrates new theories on how to abstract large urban heterogeneous networks with indoor small cells. It also reports on advanced applications such as train and car transmissions to demonstrate the tools' capabilities.

Studienarbeit aus dem Jahr 2003 im Fachbereich BWL - Personal und Organisation, Note: 1,3, Hochschule Ansbach - Hochschule fur angewandte Wissenschaften Fachhochschule Ansbach (Fachbereich Wirtschafts- und Allgemeinwissenschaften ), Veranstaltung: Personalbeschaffung und -marketing, 26 Quellen im Literaturverzeichnis, Sprache: Deutsch, Abstract: Arbeitszeitverkurzung, Teilzeit, Arbeitszeitkonten, Schichtdienst und innovative Arbeitszeitmodelle - all dies sind Schlagworte des zunehmenden Trends, die Arbeitszeit immer weiter zu flexibilisieren. Wahrend vor einigen Jahren noch die Mehrheit der Arbeitnehmer ihre Arbeitskraft den Unternehmen von 8-17 Uhr zur Verfugung stellte, ist in jungster Zeit durch die Verlangerung der Ladenoffnungszeiten, die Zunahme des Dienstleistungsangebots und den verstarkten Wettbewerb der Anteil der Arbeitnehmer mit festen Arbeitszeiten rapide gesunken. Fur die Arbeitnehmer bedeutet dies einen direkten Eingriff in ihre personliche Lebenssituation. Die zeitliche Verplanung bestimmt ihre Moglichkeiten, ihre Freizeitgestaltung, ihr Familienleben. Nichtbeachtung der Erkenntnisse uber menschengerechte Arbeitszeitgestaltung kann die Gesundheit der Arbeitsnehmer schadigen, Motivation und Leistungsfahigkeit konnen stark nachlassen.1 Nur durch eine professionelle und durchdachte Personaleinsatzplanung ist es moglich, diese negativen Effekte zu kompensieren und den Mitarbeitern auch die positiven Seiten der Arbeitszeitflexibilisierung zuganglich zu machen. Zielsetzung dieser Studienarbeit ist es, einen Teilbereich der Personalplanung, die kurzfristige Personaleinsatzplanung, naher zu beleuchten. Im zweiten Teil der Arbeit sollen die Grundlagen erarbeitet werden, im speziellen werden dies Einordnung, Definition, Ziele und Anwendungsbereiche der kurzfristigen Personaleinsatzplanung sein. Anschliessend folgt der erste Schwerpunkt der Arbeit, in welchem die Theorie der kurzfristigen Personaleinsatzplanung dargelegt wird. Der zweite Schwerpunkt, die p
