Design and Implementation of 800Mbps 16-QAM Pulse Shaping Filter in the Satellite High Speed Transmission
This paper presents the design procedure and implementation result of 800Mbps 16-QAM pulse shaping filter for payload data transmission system of remote sensing satellite. In order to achieve the high speed pulse shaping filter adapting to the current hardware components, the 16-QAM constellation mapping and the pulse shaping have been combined. Meanwhile, the poly-phase structure of FIR and the distributed algorithm based on look-up table have been used in favor of high speed shaping filter calculation in FPGA. In addition, the 800Mbps 16-QAM pulse shaping filter prototype is realized on the hardware by using the parallel circuit architecture and the high speed circuit technique. The test results have been shown to prove that the design method of the pulse shaping filter can be effectively applied to the high speed payload transmitter of remote sensing satellite.
