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.

Detection and Estimation of a Spectral Line in MIMO Systems [link]

We consider the problem of detecting and estimating radio channel dispersion parameters of a single specular multipath component (SMC) embedded in spatially correlated noise from observations collected using a MIMO measurement setup. The corresponding detection threshold versus the false alarm probability is derived from $\chi^2$-random field with two degrees of freedom defined over a 5-dimensional dispersion space using the theoretical framework of the expected Euler characteristic of random excursion sets. We show that the probability of false alarm is in excellent accordance with the relative-frequency of estimating false alarms using a maximum likelihood estimator and detector for acquiring the 5-dimensional dispersion parameter vector of the SMC.
