摘要
智能天线通过多根天线之间的相干操作,可以使得信号向固定方向传输,从而扩大信号的覆盖范围,提升信号的传输距离,从而提升整个无线通信系统的性能。在第三代移动通信系统中,智能天线技术已经相对完备了,在第四代移动通信系统中,第四代天线还有着一定的缺陷,不能满足TD-LTE网络的需求。为了更好地提升4G网络的性能,本文重点分析了智能天线,详细阐述了其对TD-LTE网络的意义。
Smart antennas can transmit signals in a fixed direction through the coherent operation of multiple antennas,thus expanding the coverage of signals and increasing the transmission distance of signals,thereby improving the performance of the whole wireless communication system. In the third generation mobile communication system,smart antenna technology is relatively complete. In the fourth generation mobile communication system,the fourth generation antenna still has some defects,which can not meet the needs of TD-LTE network. In order to improve the performance of 4 G network better,this paper focuses on the analysis of smart antenna and elaborates its significance to TD-LTE network.
