Antwerp space won the ESA ITT for DVB Carrier ID Detection and Demodulation (DVB-CIDD) and kicked-of the project in July 2016. Alongside the existing activity with ESA for on-board Spectrum Monitoring (OBSM), this new project forms an important additional thread towards the development of a fully featured on-board interference detection and reporting system.
Industry recently standardized on DVB-CID with the purpose of detecting the presence of unintentional sources of interference. One of the main sources of service interruptions in broadcasting or professional communication links, is the presence of unintentional interferers, which are accidentally transmitting towards another transponder e.g. erroneous dish pointing or broken BUC (block up-converter) sweeping in frequency. The DVB-CID consists in a spread-spectrum signal to be transmitted by all new satellite modulator equipment in order to allow their identification.
In this project Antwerp Space will implement the required receiver technologies to detect multiple DVB-CID signals and verify the effectiveness of current technologies in various realistic interference scenarios. The activity will enhance and improve the capability for detecting the presence of unwanted transmitter signatures.
The activity includes defining the typical scenarios of disrupted RF channels. These scenarios will be used to determine the requirements of the DVB-CID demodulator techniques, followed by a hardware implementation of a prototype receiver that is able to detect the interfering signals.
Finally, the activity also includes a laboratory demonstration of the effectiveness of the developed technology in the DVB-CID receiver to meet the challenges of typical satellite scenarios with unintentional jammers.
The project is expected to conclude by mid-2018.
