摘要
基于工业和信息化部及国际电信联盟(International Telecommunication Union,ITU)关于动中通/移动平台地球站发射信号的等效全向辐射功率(Equivalent Isotropically Radiated Power,EIRP)谱密度要求,以及高清视频应用对于传输速度的要求,以两种典型小口径终端为例,分析其使用亚太6D、中星16进行高清视频应用时对相关传输要求的满足情况。结果表明,小口径终端进行高通量卫星(High Throughput Satellite,HTS)高清视频应用时,采用扩频方式降低功率谱密度是避免邻星干扰的一种有效手段。
Based on the Ministry of Industry and Information Technology of the People's Republic of China and the International Telecommunication Union(ITU)regarding Equivalent Isotropically Radiated Power(EIRP)spectral density requirements for signals transmitted by earth stations on mobile/mobile platforms,and transmission speed requirements for high definition video applications,two typical small-caliber terminals are taken as examples in this paper.This paper analyzes the transmission requirements of AP6D and VX16 for high definition video applications.The results show that using spread spectrum to reduce the power spectral density is an effective means to avoid the interference of neighboring stars in the application of High Throughput Satellite(HTS)high definition video with small aperture terminals.
