In 2000, the Signal Processing and Speech Communication Laboratory (SPSC Lab) of Graz University of Technology (TU Graz) was founded as a research and education center in nonlinear signal processing and computational intelligence, algorithm engineering, as well as circuits & systems modeling and design. It covers applications in wireless communications, speech/audio communication, and telecommunications.

The IMS student design competitions are an annual event at the IEEE MTT-S International Microwave Symposium. In 2017, the SPSC lab members Harald Enzinger and Karl Freiberger won the first prize in the competition "Power Amplifier Linearization through Digital Predistortion". The aim of this competition was to linearize a highly efficient but nonlinear envelope tracking power amplifier in dual-band operation by means of digital predistortion. The winning solution combines several state-of-the-art methods for crest factor reduction (CFR) and digital predistortion (DPD) with new extensions, developed specifically for this competition. You can find out more about this winning solution in the Jannuary/February issue of the IEEE Microwave Magazine. A preprint version of the paper can be downloaded from the SPSC website.
