Welcome!
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.

Adaptive Multipath-Based SLAM for Distributed MIMO Systems
Localizing users and mapping the environment using radio signals is a key task in emerging applications such as reliable, low-latency communications, location-aware security, and safety-critical navigation. Recently introduced multipath-based simultaneous localization and mapping (MP-SLAM) can jointly localize a mobile agent (i.e., the user) and the reflective surfaces (such as walls) in radio frequency (RF) environments with convex geometries. Most existing MP-SLAM methods assume that map features and their corresponding RF propagation paths are statistically independent. These existing methods neglect inherent dependencies that arise when a single reflective surface contributes to different propagation paths or when an agent communicates with more than one base station (BS).
