The Digital Signal Processing Competence Center tries to answer the challenge of maintaining a strong position for telecommunication systems and satellite observation in the European industry. It allows the whole value chain of the space industry (operators, System Manufacturer, equipment suppliers and component suppliers) to develop their market by reducing the risks connected to the introduction of new technologies and favoring standardization initiatives.
It focuses on digital technologies used in broadband telecommunications on optical support and radio, and on remote detection of radio signals and image acquisition. It also helps meet the challenges of an increase in the frequency of communications and the rarefication of radio resources due to bandwidth requirements. This covers their integration within telecommunications and observation systems. In order to respond to 5G or Internet of Things requirements, the center builds the technological blocks needed to optimize system performance, both in terms of transmission layers in the form of a processing chain, and in terms of network layers through introduction of virtualization technologies (NFV) and network programming (SDN). For future broadband transmissions, the center is working on the use of free-space optical communication (FSO) offering an abundant spectrum resource.
The applications concerned are the broadcasting of content by satellite, access to broadband multimedia systems for all (video, sound, internet), universal support of Internet of Things with worldwide cover and an optimized and more direct access to images for professional requirements.
