Simulation analysis of low-orbit satellite communication performance based on DVB-S2X protocol
The DVB-S2X protocol is introduced,and the basic principles of higher-order modulation tech-nique and constellation mapping are analyzed.A simulation model of low-orbit satellite communication based on DVB-S2X protocol is constructed on the basis of satellite-to-ground link analysis.Simulation experiment is car-ried out for the 16APSK,32APSK and 64APSK of the DVB-S2X protocol.The bit error rate and frame loss rate are used as indicators to analyze the communication performance.
