Department of Signal Processing for Mobile Information Systems

The Department of Signal Processing for Mobile Information Systems performs research and international standardization in the field of speech and audio signal processing, pattern recognition, and document processing. In speech and audio processing we are mainly interested in methods of speech enhancement, noise reduction, acoustic echo cancellation, artificial bandwidth extension as well as instrumental speech quality measures. Our application areas cover car and office communications, hearing aids, hands-free systems, gateways, and mobile phone chipsets. A further research area is robust decoding methods for speech and audio. In the field of pattern recognition and document processing we are deeply involved in Arabic handwriting recognition and in online quality control of production processes.
