Guest lecturer Dr. Oliver Lang at TKP meeting

Title: Joint Communications and Sensing with OFDM

Lecturer: Dr. Oliver Lang

Institute of Signal Processing, Johannes Kepler University Linz, Austria

Time: October 17, 2025: 10:00 – 11:00 (TKP meeting, online)

Abstract of the talk

Orthogonal frequency-division multiplexing (OFDM) is the preferred waveform for modern communication standards such as 5G. Beyond its well-known advantages, OFDM also enables environmental sensing around the antenna, making it a strong candidate for future joint communication and sensing systems. However, compared to traditional sensing waveforms such as frequency-modulated continuous wave (FMCW), it faces certain drawbacks, including higher sampling frequency requirements and increased memory consumption. In this talk, I will present my research from recent years, which has focused on addressing these challenges and mitigating the limitations of OFDM for sensing in comparison to FMCW.

Biography

Oliver Lang was born in Schärding, Austria in 1987. He studied Electrical Engineering at the Vienna University of Technology and received his Bachelor degree in 2011. In the next two years Oliver Lang studied microelectronics at the Vienna University of Technology and finished it with excellent success. The topic of his master thesis was the development and analysis of models for a scanning microwave microscope. From 2014 until 2018, he was a university assistant at the Institute of Signal Processing, Johannes Kepler University Linz, where he received his Ph.D. in 2018. The title of his dissertation is “Knowledge-Aided Methods in Estimation Theory and Adaptive Filtering”, where he invented several interesting estimators and adaptive filters for special applications. From 2018 until 2019 he worked at DICE GmbH in Linz, which is a subsidiary company of Infineon Austria GmbH. Since March 2019, he is a university assistant with Ph.D. at the Institute of Signal Processing.
