| 摘 要： | 针对互耦对空域相关性影响的两种对立观点,分别应用不同的互耦补偿方法修正多天线系统的传输矩阵,推导出容量公式。通过电磁场数值方法并结合蒙特卡罗实验,指出了在射线模型下互耦对容量的作用需取决于入射波的角谱分布,随着中心到达角的变化,互耦从一个积极的因素变化成一个消极因素。在Kronecker信道模型下,通过数值计算证明了天线方向图相关与互耦矩阵补偿方法是等效的,从而统一了两种对立观点,完善了互耦对相关性作用的研究。

| Abstract: | Aiming at the two contrary viewpoints about the effects of mutual coupling on spatial correlation,two mutual coupling compensation techniques are employed to derive the channel capacity of multi-antenna system. Based on the electromagnetic numeric method and Monte Carlo method,it is pointed out that the effects of mutual coupling are also determined by the spatial channel parameters under the ray tracing model. As the mean angle of arrival varying,the effects of the mutual coupling will change from a detrim... |
