Erik Sausa
@eriksausa
I build RF signal-processing and Bayesian tracking systems from SDR data.
SlovakiaWhat I'm looking for
I've developed distributed Bayesian target-tracking methods at TU Wien, including Likelihood Consensus 2.0, reducing inter-agent communication overhead by approximately 190× while maintaining centralized-grade posterior accuracy. This work led to publications in Elsevier Signal Processing and IEEE ICASSP.
I've also built a 1090 MHz ADS-B SDR receiver pipeline and implemented 5G physical-layer feedback and Doppler compensation for the Vienna 5G Link/System Level Simulator using MATLAB and C++.
I combine RF and digital baseband engineering with Bayesian inference, technical reporting, client relations, operations management, and multilingual team leadership.
