Signal processing for Wireless and Mobile Communication

Seminar on "Signal processing for Wireless and Mobile Communication"

Wireless communication

There is no secret that XXI century has started under the sign of information boom. The total computerization and globalization of the economy is still bringing this boom higher and higher. Such an increase requires development of the devices capable of delivering information everywhere and processing it as fast as possible.

Recently mobile wireless communication systems seem to outpace other means of information exchange mainly due to the ubiquity of electromagnetic waves and necessity to access information "anytime and anywhere". However this advance doesn't come for free. The new generations of wireless systems bring new requirements to satisfy ever increasing consumer demands for high speed data transfers (up to 2Mbits/s), video, multimedia as well as voice traffic to mobile users. This all creates a need for more powerful and efficient algorithms for modulation schemes, coding, power control, and detection techniques.

Organization

The seminar is organized by the Signal Processing and Speech Communication Laboratory at the Institute for Communications and Wave Propagation of TU Graz. Students will work on a selected topic, create a self-study WWW document, and give an oral presentation in class during a 45 minute discussion session. Work in small groups of 2 or 3 students is strongly encouraged.  Remote participation via telecooperation tools and IP video-conferencing will be supported. The working language will be English.
