摘要
介绍了DVB-S2X标准,重点分析了其中高阶调制技术的基本原理和星座映射,在进行星地链路分析的基础上,构建了 DVB-S2X标准低轨卫星通信仿真模型,针对DVB-S2X标准中16APSK、32APSK、64APSK调制信号开展仿真试验,以误码率和丢帧率为指标进行通信性能分析.
Abstract
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.
