DVB-CID (Digital Video Broadcast - Carrier Identification System) is an ETSI standard for interference prevention within digital data transmission via satellites that was first published in 2013. Its goal is the identification of interfering transmissions from other sources, in order to respond to Radio Frequency Interference (RFI).
The DVB-CID high performance modulator can be configured by a simple configuration interface and outputs a baseband signal split into real and imaginary part.
