解析未来移动通信系统中的智能天线技术

Analysis of the smart antenna technology in future mobile communication systems

如何消除同信道干扰(CCI)、多址干扰(MAI)与多径衰落的影响是提高无线移动通信系统性能的主要因素。智能天线利用数字信号处理技术,产生空间定向波束,使天线主波束对准用户信号到达方向,旁瓣或零陷对准干扰信号到达方向,可以达到高效利用移动用户信号并抑制干扰信号的目的。

How to eliminate the same channel interference （CCI）, multi-access interference （MAI） and multi-path fading into the impact of people in the wireless mobile communication system to improve performance when the main factors to consider. Smart antennas using digital signal processing technology, have a directional beam space, so that the main antenna beams of the signal to reach users at the direction of the side-lobe zero or settlement arrived at the direction of signal interference, which would achieve efficient use of signals and make mobile users suppress interference signals.
