国际海事卫星移动通信系统与下一代IMT系统在扩展C频段的共存

根据《中华人民共和国无线电频率划分规定》和国际电信联盟《无线电规则》的相关规定可知,在我国第四代国际海事卫星移动通信系统的空对地（下行）链路与下一代IMT系统存在频率重叠。为了保证第四代国际海事卫星移动通信系统与下一代IMT系统在扩展C频段的共存,给出了使上述两系统正常工作的前提条件或保护措施。通过理论分析、仿真计算以及调研厂商的制造水平,给出了关于第四代国际海事卫星移动通信系统与下一代IMT系统在扩展C频段共存的建议。...

Summary:根据《中华人民共和国无线电频率划分规定》和国际电信联盟《无线电规则》的相关规定可知,在我国第四代国际海事卫星移动通信系统的空对地（下行）链路与下一代IMT系统存在频率重叠。为了保证第四代国际海事卫星移动通信系统与下一代IMT系统在扩展C频段的共存,给出了使上述两系统正常工作的前提条件或保护措施。通过理论分析、仿真计算以及调研厂商的制造水平,给出了关于第四代国际海事卫星移动通信系统与下一代IMT系统在扩展C频段共存的建议。
Bibliography:According to the ＂Table of Frequency Allocations of People＇s Republic of China＂ and the relevant provisions of the ＂Radio Regulations＂, it is shown that there are frequency overlap between the space to ground（down）link of the fourth-generation international maritime satellite（INMARSAT） mobile communication system and the next generation international mobile telecommunication（IMT） system in China. In order to guarantee the coexistence of the fourth-generation INMARSAT mobile communication system and the next generation of IMT system, the operation prerequisites or protection distances were analyzed. Based on the theoretical analysis, the simulation and survey of production level of equipment company, some suggestions on how to make the above two systems coexist were presented.
