DBBC3: VLBI at 32 Gbits per second
Paper in proceeding, 2012
The project to develop the third generation of a digital backend system (DBBC3) for VLBI and other applications is presented, including an overview of the evolution of this system. The initial development started about ten years ago and evolved in the course of time by improving all its components: hardware, firmware and software going from DBBC1 to DBBC2. The latest, now third generation will be able to fully implement digitally all the functionality required of a complete 32 Gbps VLBI backend for the EVN and VLBI2010. The architecture and adopted methods are described. The implementation of the astronomical version is financially supported by RadioNet3.
