摘要 为了在＂数字红利＂频段（698～806MHz）部署时分-长期演进系统,提出一种不同系统兼容的确定性分析方法。基于频谱占用度实测数据,该方法依据第三代合作伙伴计划和中国广播行业标准所提供的频谱模板,根据干噪比（I/N）保护准则,分析时分-长期演进系统与广电系统的邻频共存条件。数值仿真结果表明,当满足所需的频率隔离和空间隔离条件时,两系统可以邻频共存。 In order to deploy Time Division Long Term Evolution （TD-LTE）system in the“digital divi-dend”band （698～806 MHz）,a kind of analysis method which is about the system compatibility be-tween different systems is put forward.Based on the measured data of the spectrum occupancy,with ref-erence to the spectral masks which are provided by the 3rd Generation Partnership Project （3GPP）and Chinese broadcasting industry standard,and according to interference and noise ratio （I/N）protection criterion,the conditions of TD-LTE system and broadcasting system adjacent coexisting are analyzed. Numerical simulation results show that when the frequency of isolation and spatial isolation conditions meet the requirements,two system can coexist in adjacent frequency.
