Team MarmotE has been actively involved with intelligent spectrum sharing technologies since 2013. We participated in the first DARPA Spectrum Challenge and took first place in the competitive tournament and fourth place in the cooperative race during the Preliminary Event in 2013. We took third place in the collaborative tournament in the Final Event and made it to the semifinals in the competitive race in 2014.

We also qualified and are particiapting the DARPA Spectrum Collaboration Challenge. Our team was the overall winner at the Phase1 Tournament in December, 2017.


Our solutions are built on multiple novel RF physical layers (modems), a flexible software architecture for implementing cross-layer optimizations and intelligent autonomous communication strategies. We use GNURadio with heavily optimized intrinsics, RFNoC and Xilinx High Level Synthesis for developing robust and high performance radios.

We are active members of the SC2 Collaboration Interface Language Council (CILC) with significant contributions to the collaboration protocol and supporting tools. Our current radio solution reliably collect and distribute collaboration information (channel usage, incumbent status, node positions, etc.) within the network and collaborate with our peers using the CIL protocol.


The team has four members from Hungary and the US. Miklos Maroti, a mathematician at the University of Szeged, is the main architect and the most active developer of our team. Peter Volgyesi, a research scientist at Vanderbilt University is the administrative lead of the team. Our initial involvement with the Spectrum Challenge was motivated by his NSF NeTS project. Sandor Szilvasi, an RF and FPGA engineer with strong data visualization skills, is focusing on tool support and performance evaluation of our design.Peter Horvath is an RF and digital communication expert with deep theoretical background in these domains.
