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.

Multipath-based Localization and Tracking considering Off-Body Channel Effects [link]
In this work we consider multipath-based positioning and tracking in off-body channels. We analyse the effects introduced by the human body and the resulting effects that are of interest in positioning and tracking based on channel measurements obtained in an indoor scenario. As the signal bandwidth is known to effect the achievable accuracy in positioning, the bandwidth dependency of the field of view (FOV) induced by human body via shadowing and the number of multipath components (MPCs) detected and estimated by a deterministic maximum likelihood (ML) algorithm is investigated. A multipath-based positioning and tracking algorithm is proposed that associates estimated MPC parameters with floor plan features and exploits a human body-dependent FOV function. The proposed algorithm is able to provide accurate position estimates even for an off-body radio channel in a multipath-prone environment with the signal bandwidth found to be a limiting factor.Contact: Thomas Wilding, Erik Leitinger
