Die vorliegende Arbeit beschreibt ein Konzept zur Optimierung mobiler Antennensysteme. Die sogenannte Antennensynthese bestimmt mithilfe von simulierten oder gemessenen Übertragungskanälen optimale feste Richtcharakteristiken. Diese steigern die spektrale Effizienz und die Zuverlässigkeit des Antennensystems gegenüber herkömmlichen Antennen mit omnidirektionalen Richtcharakteristiken. Hierfür werden die Antennensysteme bestmöglich an die Vorzugsrichtungen des Kanals angepasst. This work describes an optimization concept for mobile antenna systems. The so-called antenna synthesis determines optimal fixed antenna radiation patterns with the help of simulated or measured transmission channels. These radiation patterns increase the spectral efficiency and the reliability of the antenna system compared to conventional antennas with omnidirectional radiation patterns. Therefor the antenna systems are matched as best as possible to the predominant directions of the channel.

Mobile robotic systems need to perceive their surroundings in order to act independently. In this work a perception framework is developed which interprets the data of a binocular camera in order to transform it into a compact, expressive model of the environment. This model enables a mobile system to move in a targeted way and interact with its surroundings. It is shown how the developed methods also provide a solid basis for technical assistive aids for visually impaired people.
