(Preliminary): The Orthogonal Frequency Division Multiplexing
(OFDM) digital transmission technique has several advantages in
broadcast and mobile communications applications. The main
objective of this book is to give a good insight into these
efforts, and provide the reader with a comprehensive overview of
the scientific progress which was achieved in the last decade.
Besides topics of the physical layer, such as coding, modulation
and non-linearities, a special emphasis is put on system aspects
and concepts, in particular regarding cellular networks and using
multiple antenna techniques. The work extensively addresses
challenges of link adaptation, adaptive resource allocation and
interference mitigation in such systems. Moreover, the domain of
cross-layer design, i.e. the combination of physical layer aspects
and issues of higher layers, are considered in detail. These
results will facilitate and stimulate further innovation and
development in the design of modern communication systems, based on
the powerful OFDM transmission technique.

Die digitale Nachrichtenubertragung gehort heute zu den wichtigen
Wachstumsbranchen. Um die Mobilitat des einzelnen noch weiter zu
erhohen, werden z. B. Sprache oder Bilder in digitaler Form auch
uber Funkstrecken zu den mobilen Empfangern ubertragen. Bereits
vorhandenen Funkdiensten wie D-Netz, E-Netz, Digital Audio
Broadcast (DAB) oder Digitales Satelliten Radio (DSR) werden
weitere folgen. Datenfunkstrecken sind sehr fehleranfallig; auch
das Funkkanalverhalten kann sich aufgrund der Teilnehmerbewegung
zeitlich sehr schnell andern. Deshalb ist hier die Anwendung von
Fehlerkorrekturverfahren unverzichtbar. Das Buch gibt eine
Einfuhrung in die Methoden der Kanalcodierung zum Zwecke der
Fehlerkorrektur. Ausgehend von der Shannonschen Informationstheorie
werden Codier- und Decodierverfahren fur Block- und Faltungscodes
diskutiert und anschaulich beschrieben. Es wird eine digitale
Ubertragungsstrecke von der Quelle bis zur Senke betrachtet
einschliesslich der grundlegenden digitalen Modulationsverfahren.
Das Buch ist im Rahmen des MeDoc-Projektes (http:
//medoc.informatik.tu-muenchen.de/deutsch/medoc.html) in die
elektronische Informatik-Bibliothek aufgenommen worden."
