Abstract

Implementation of Long Term Evolution (LTE) 700 in Indonesia is feasible given the fact of 700 MHz spectrum availability in certain geographical rural areas. Also known that the spectrum allocation is adjacent to Analog Television (ATV) frequency which using PAL-G systems. Thus, the interference analysis on coexistence between ATV and LTE to define the minimum requirement of protection distance and guard band has to be taken into account. Therefore, according to the allowable C/I (protection ration) between these two services, the exact requirement has been simulated using SEAMCAT (Spectrum Engineering Advanced Monte-Carlo Analysis Tool) software. Several scenarios in SEAMCAT between ATV and LTE such as different direction of link have been taken. As a result, ATV and LTE can operate without disturbing each other by having 20 MHz with geographical distance radius of 5 km, 15 MHz with radius of 10 km or 10 MHz with radius of 40 km. The result could be used as a guideline in making plan for the coexistence between LTE and PAL-G in UHF band.

模拟电视(PAL-G)与LTE (E-UTRA)在UHF频段的干扰分析

鉴于在某些地理上的农村地区有700兆赫频谱可用性，在印度尼西亚实施长期演进(LTE) 700是可行的。还知道频谱分配与使用PAL-G系统的模拟电视(ATV)频率相邻。因此，必须考虑对ATV与LTE共存的干扰分析，以确定保护距离和保护频带的最小要求。因此，根据这两种服务之间允许的C/I(保护比率)，使用seamat(频谱工程高级蒙特卡罗分析工具)软件模拟了确切的要求。在ATV和LTE之间的seamat中，采用了不同的链路方向等多种场景。因此，ATV和LTE可以在地理距离半径为5公里的范围内分别拥有20 MHz、10公里范围内的15 MHz、40公里范围内的10 MHz，互不干扰。研究结果可为UHF频段LTE与PAL-G共存的规划提供参考。
