TD-LTE系统中智能天线技术的优化摘要 在3G系统中,智能天线已得到了成熟而广泛的应用,但在TD-LTE系统中,它还存在一定的不足,不能满足4G网络的需求。为了尽可能提升TD-LTE 系统的性能,本文从智能天线的信号模型、MIMO技术、波束赋形技术及算法等方面介绍了智能天线技术的优化方案,并对比了3G 与4G系统中不同算法的优劣性,最后得出EBB算法在TD-LTE 系统中有较好的特性,能够最大限度地提升TD-LTE系统的性能,从而满足用户的需求。关键词:TD-LTE;智能天线;波束赋形;MIMO技术;EBB算法Abstract: in 3G system, smart antenna has been a maturely and widely used, but in the TD-LTE system, it also poses a low, can not meet the requirements of the 4G network.
