Abstract
This paper presents a three-dimensional (3D) massive multiple-input and multiple-output (MIMO) antenna array model, which includes the spherical array assumption and geometric properties for future fifth generation (5G) wireless communications. A parametric approximation algorithm is developed for estimating the spatial fading correlations (SFCs) and channel capacities of the 3D massive MIMO antenna array systems under different power angular spectrum (PAS). The relationship between correlation with the spacing of antenna arrays and angular parameters was classified. The results show that the simulation values of the approximate method fit the theoretical calculation very well, thereby validating the feasibility of the proposed 3D large-scale massive MIMO model.

For the proposed 3D large-scale arrays, we assume the incident signals are uniformly distributed in the elevation and azimuth planes, i.e., θ and φ are uniformly distributed over the range of angles [θM − θ, θM + θ ]. and φM − φ, φM + φ . θ and φ are the elevation spread (ES) and azimuth spread (AS), respectively; θM and φM are the mean azimuth of arrival (MAOA) and mean elevation of arrival (MEOA), respectively

It is confirmed in [15] that the UCCA array antenna shown in Fig. 1(b) can effectively solve this problem In this case, the signal spherical wavefront assumption is proposed, the channel impulse response of MIMO antenna arrays can be separated into steering-vector-dependent and timedependent components [13], which can be expressed as.
