自适应天线技术因为其高度的灵活性和可靠性在无线通信系统中已经逐渐成为了一项关键的技术。它是在空域和时域变化较为严重的传播环境中克服多径衰落的一种有效解决方案。人们利用自适应阵列天线将空时域的多径信号合并以达到对干扰的抑制。文中首先通过空域相关矩阵特征值分解的方法对无线通信环境进行分类 ,然后根据不同的情况给出相应的处理方案 ,实现了自适应阵列天线的动态配置
Adaptive antenna technology has gradually become a key technology in wireless communication systems because of its high degree of flexibility and reliability. It is an effective solution to overcome multipath fading in the more airspace and time-domain propagation environment. People use adaptive array antennas to merge the multipath signals in the space-time domain to achieve the interference suppression. Firstly, the wireless communication environment is classified by the method of eigenvalue decomposition of airspace correlation matrix, then the corresponding processing scheme is given according to different situations, and the dynamic configuration of adaptive array antenna is realized
