700MHz频段DTMB与LTE系统兼容性测试研究

Compatibility Research on DTMB and LTE Systems within 700MHz Band

随着广播电视业务的不断发展,地面电视的频谱资源日益紧张。与此同时,其他无线电业务也在争取更多的无线电频谱资源来确保其业务应用和发展。尤其是近些年来,宽带无线移动通信技术的迅猛发展,对频率资源提出了更多的需求。为了保证地面广播电视业务的顺利开展,有必要对该频段LTE业务与地面数字电视业务之间的兼容性问题展开深入研究,本文主要对DTMB系统受LTE系统干扰时的相关兼容性参数开展测试研究。

With the development of broadcasting service, the frequency resource of terrestrial television becomes strained. Meanwhile, there are also great requirements on frequency resource for other services, in order to assure their application and development. Especially in recent years, the rapid progress of broadband wireless mobile causes the demand for more frequency resource. For the sake of broadcasting service＇s normal operation, it is necessary to carry on compatibility research on DTMB and LTE systems. In this paper, we study the compatibility technical param- eters for LTE interfering with DTMB.
