摘要
本文基于对自适应天线协方差矩阵特征结构的分析,推导出了考虑阵元间互耦时的自适应天线最佳权矢量的解析表达式。阐明了互耦导致自适应天线系统性能下降的机制,最后提出了一种有效的互耦校正方法。
In this paper, the analytical expression of the optimum weight vector in the adaptive antennas, taking into account the mutual coupling existing between elements, is derived by analyzing the eigenstructure of covariance matrix, and the mechanism of the performance degradation due to mutual coupling is investigated. Finally, an efficient method of mutual coupling compensation in adaptive antennas is proposed.
