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.

Robust indoor positioning at sub-meter accuracy typically requires highly accurate radio channel measurements to extract precise time-of-flight measurements. Emerging UWB transponders like the DecaWave DW1000 chip offer to estimate channel impulse responses with a reasonably high bandwidth, yielding a ranging precision below 10 cm. The competitive pricing of these chips allows scientists and engineers for the first time to exploit the benefits of UWB for indoor positioning without the need for a massive investment into experimental equipment.
 
The figure illustrates the employment of multipaths (numbers 1-5) to estimate the agent's position using a single channel-impulse-response measurement only. The colored dots represent the evaluated likelihood where brighter indicates a better model fit regarding the observation.
