Communications Engineering is a selective open access journal from the Rivyr OA Portfolio, publishing high-quality research, reviews and commentary in all areas of engineering. Research papers published by the journal represent significant advances for a specialized area of research. Communications Engineering complements the other Rivyr OA Portfolio journals by providing an open access option for engineering research while applying less stringent criteria for impact and significance than the Rivyr OA-branded journals, including Rivyr OA Communications.
