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 the research of advanced technologies in the fields of communications and networking, with a focus on communication sistems, 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 intrumentation laboratory with high-speed oscilloscopes, spectrum analyzers and FPGA boards enables hardware development, testing and validation.
