摘要:

为分析在1 518~1 525 MHz频段附近部署IMT系统的可行性,在梳理了国际电信联盟建议书和《无线电规则》的基础上,通过理论分析和仿真计算等手段,就1 492~1 518 MHz频段IMT系统对1 518~1 525 MHz频段卫星移动系统的干扰问题进行了深入分析。针对IMT 系统基站对卫星移动系统终端在不同场景下的干扰链路,采用蒙特卡洛仿真方法对阻塞干扰与邻频干扰进行计算仿真。仿真结果给出了不同场景下的阻塞干扰概率以及两个系统邻频共存的条件。研究结果可为我国无线电管理部门对该频段邻频的未来规划提供理论支撑。

Abstract:

In order to analyze the feasibility of deploying mobile satellite system below 1 518~1 525 MHz band,the interference from the IMT system in 1 492~1 518 MHz band to the mobile satellite system in 1 518~1 525 MHz band was studied in detail via theoretical analysis and simulations based on the combing of the ITU recommendations and radio regulation.Aiming at the interference link from IMT base station to the terminal of mobile satellite system in different scenarios,the Monte Carlo simulation method was used to calculate the blocking and the adjacent channel interference.The interference blocking probability and the coexisting conditions between the two systems in adjacent band were given in the simulation results.The conclusion can be used to support the planning of adjacent band by national radio management department.
