Ground based high data rate DVB-S2 demodulator for high data rate AISR transport

摘要

The Wideband Global SATCOM system (WGS) block II satellite offers Airborne Intelligence, Surveillance, and Reconnaissance platforms with an unprecedented amount of satellite bandwidth. Unmanned aerial vehicle (UAV) platforms require a new waveform and subsequent modem implementations to fully exploit these new capabilities. To complement the high data rate (HDR) version of the Digital Video Broadcasting, Second Generation Satellite (DVB-S2) standard waveform and the single FPGA modulator introduced in previous work, this paper will focus on the implementation of a matching HDR ground-based demodulator. The implementation described within leverages commercial off the shelf (COTS) technology, to deliver a low risk, scalable, and portable design.
