[DOI, BibTeX, Details...]Bastian Bloessl defended his PhD thesis, titled A Physical Layer Experimentation Framework for Automotive WLAN, and graduated summa cum laude from Paderborn University.
The thesis contains a comprehensive overview of our WLAN transceiver and research projects that were facilitated by our WLAN transceiver.
Our paper *mSync: Physical Layer Frame Synchronization Without Preamble Symbols* was just accepted for publication in the IEEE Transactions on Mobile Computing.
In the paper, we propose a frame format and a corresponding decoding strategy that does not rely on dedicated preamble symbols. To evaluate our approach, we implement the algorithm for a custom low-power PHY, but also for the IEEE 802.15.4 O-QPSK PHY.

One core assumption of many network simulators is that interference and noise have a similar impact on the performance of the physical layer. We were curious if this is actually the case and conducted simulations as well as experiments in an SDR-based testbed. The results will be published at IEEE VNC 2017 in Torino, Italy.

[DOI, BibTeX, PDF and Details...]We used our WiFi transceiver implementation to study the impact of noise and interference on IEEE 802.11p. Whether there is a significant difference between noise and interference is very relevant for networks simulations, which often use very simplistic simulation models for the physical layer.
