An ECE team led by WINLAB Associate Director Ivan Seskar along with graduate students Ratnesh Kumbhkar and Dragoslav Stojadinovic has won the $750K 5th place prize at the DARPA Spectrum Collaboration Challenge (SC2). The SC2 is the first-of-its-kind collaborative machine-learning competition to overcome scarcity in the radio frequency (RF) spectrum. The team from Rutgers in partnership with IMEC of Belgium (an R&D and innovation hub in digital technologies) developed a collaboration scheme called SCATTER that promotes collaboration to overcome spectrum scarcity. Ratnesh Kumbhkar is a PhD student working under the supervision of Distinguished Professor Narayan Mandayam and Ivan Seskar.
