Abstract:
In communications, wireless channels are often modelled as linear time-invariant (LTI) systems. However, real wireless channels have time-varying characteristics. This thesis is devoted on developing methods to transmit data over linear time-varying (LTV) channels. In the formal analysis of LTV systems time-frequency representations, and in particular Gabor frames, play a key role. Thus, parts of the thesis are dedicated on the study of finite Gabor frames and their properties.
Translated abstract:
In der Kommunikationstheorie werden drahtlose Kanäle oft als zeitinvariante lineare (LTI) Systeme modelliert. Jedoch weisen reale Kommunikationskanäle zeitvariante Eigenschaften auf. Diese Arbeit widmet sich der Entwicklung von Methoden zur Übertragung von Daten über zeitvariante Kanäle. Bei der formalen Untersuchung von zeitvarianten Systemen spielen Zeit-Frequenzdarstellungen eine Schlüsselrolle. Daher werden Eigenschaften von endlichen Gabor-Rahmen auch analysiert.
