Welcome to ComLab. We are part of the Department of Communications of the School of Electrical and Computer Engineering of the University of Campinas (Unicamp). ComLab is dedicated to cutting-edge research in the fields of communications and networking, with a focus on communication systems, signal processing, machine learning and optical transmission and networking. We have a history of collaborations with industrial partners, such as CPqD, Ericsson Research, Padtec and BrPhotonics. Our well-equipped instrumentation laboratory with high-speed oscilloscopes, spectrum analyzers and FPGA boards enables hardware development, testing and validation.
