About the Institute

Research in the Institute of Information Technology is carried by two groups. The Information Transmission Group is headed by Prof. Lindner, the Dialogue Systems Group by Prof. Minker.

The research work of the Information Transmission Group is focused on new methods for future wireless communication systems. The general goal is to contribute to the development of the theory in this field, and to find advanced techniques allowing the most efficient use of radio frequencies and transmit power. The whole work is based on vector-valued transmission models developed in the past by this group. It includes transmission over multiple-input multiple-output channels, spreading in space, time and frequency, coherent and non-coherent space-time and space-frequency coding, and iterative detection methods. Single carrier as well as multi carrier (orthogonal frequency division multiplexing, OFDM) modulation schemes are considered. For more details see Information Transmission.

The Dialogue Systems Group has placed its general research focus on the development and evaluation of user-friendly Spoken Language Dialogue Systems. This objective is based on the following four major aspects: robust and flexible component technologies, approaches to adaptive dialogue management and intelligent user assistance as well as evaluation and usability issues. Applications include mobile information systems as well as intelligent assistants. Major research interests span acoustic signal processing, speech recognition and understanding as well as multimodal dialogue interaction.  For more details see Dialogue Systems.

The institute contributes with lectures, laboratory courses, projects, and seminars to the education of students in various fields of study within the Faculty of Engineering and Computer Science. For more details see Teaching.
