摘要

本文推导了均匀圆阵列(UCA)三维(3D)空间衰落相关(SFC)的封闭表达式,该表达式可用于评估基于几何的随机信道模型(gbsm)。该模型的基本思想是入射波的总功率相对于功率的真实分布,并依赖于方位角传播(AS)和仰角传播(ES)。这种广义的封闭形式表达式允许在所有级别上表示ES,这使得表达式有助于检查ES在3D多输入多输出(MIMO)通道建模中提供的灵活性程度。为了使用SFC表达式最小化互耦对MIMO性能的影响,在移动站(MS)解耦过程前后对基于几何的信道进行了评估。最后,本研究证明了在高斯分布和学生t分布下,AS和ES对3D MIMO性能的共同贡献。

3D correlation function of a uniform circular array using maximum power in the direction of arrival
In this paper, we derive a closed-form expression for three-dimensional (3D) spatial fading correlation (SFC) of a uniform circular array (UCA) useful for evaluating geometry-based stochastic channel models (GBSMs). The fundamental idea of the proposed model is that the total power of the incident wave is relative to the true distribution of power and dependent on the azimuthal spread (AS) and elevation spread (ES). This generalized closed-form expression permits the presentation of ES at all levels which renders the expression helpful for examining the degree of flexibility offered by ES in 3D multi-input and multi-output (MIMO) channel modeling. To minimize the effect of mutual coupling on MIMO performance using the SFC expression, the geometry-based channel is evaluated before and after decoupling process at the mobile station (MS). Finally, the present investigations demonstrate the joint contribution of AS and ES on 3D MIMO performance under Gaussian and Student's t-distributions.
