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.


Our new book is now available!
