mSync: Frames without preambles

20 February 2018

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.

Futebol Project

Impact of Noise and Interference on IEEE 802.11p

16 November 2017

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.

WEBee: Physical-Layer Cross-Technology Communication

20 October 2017

The Impact of Noise and Interference on IEEE 802.11p

17 October 2017

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.

Accelerating our WiFi Transceiver

22 November 2016

Researchers from Uruguay did some really nice work on our WiFi transceiver. In their paper, published at the 9th Latin America Networking Conference (LANC’16), they present performance optimizations through more efficient demapping of constellation points and an alternate implementation of the viterbi decoder.

We are grateful that the authors contributed their modifications. They are already part of the current version.
