Optimization of adaptive signal processing algorithms for wireless communications is based on a model of the underlying propagation channel. In practice, this model is never known perfectly. For example, its parameters have to be estimated and are only known with significant errors.

In this book, a systematic treatment of this practical design problem is provided for signal processing in the physical layer with multiple antennas. The design of robust signal processing algorithms is based on a description of the errors and the uncertainties in the system's model. It applies...

Das Phanomen des Separatismus hat sich, wie der Zerfall der Sowjetunion und Jugoslawiens zeigt, zu einem wichtigen Faktor der internationalen Politik entwickelt. Das Buch geht der Frage nach, ob sich Sezessionen von Staaten, die demokratisch verfasst sind, rechtfertigen lassen. Ausgehend von einer kritischen Analyse der aktuellen philosophischen und volkerrechtlichen Diskussion wird eine eigene Legitimationstheorie entwickelt. Unter Berufung auf die grundlegenden Werte moderner Demokratien argumentiert der Autor fur die Anerkennung eines Sezessionsrechts.

Endoscopic ultrasound (EUS) is now considered one of the most essential and cost-effective techniques in the assessment of a wide range of gastrointestinal diseases.
