在析出为主要衰减机制的频段内卫星固定业务对固定业务空对地干扰影响的评估方法

Methodology to evaluate the impact of space-to-Earth interference from the fixed-satellite service to the fixed service in frequency bands where precipitation is the predominant fade mechanism

ITU-R SF.1572 SPANISH-2002 发布历史

The ITU Radiocommunication Assembly considering a) that emissions from space stations in the fixed-satellite service (FSS) operating in geostationary orbit (GSO) and sharing the same spectrum as the fixed service (FS) may produce interference in receiving stations of the FS; b) results obtained using a statistical approach compared to a worst-case analysis may lead to a more efficient use of the spectrum than results from criteria developed using worst-case analysis; c) that sharing methodologies should take into consideration the performance requirements and deployment characteristics of FS systems being used and planned for use in these frequency bands; d) that in spectrum where precipitation is the predominant fade mechanism it is desirable to have an interference evaluation tool using C/N, C/I and C/(N + I) statistics to determine impact on availability; e) that such an interference evaluation tool may have application in bands above about 17 GHz to assist administrations in performing sharing studies.
