Abstract:

In order to analyze the channel characteristic of ground-air 3D-Massive MIMO system,this paper has presented a ground-air 3D-Massive MIMO channel model of geometrically-based single-bounce concentric-cylinders scattering. Compared with traditional ground-air 3D MIMO channel model, the proposed model has two improvements. First, a model for phase shift of antenna array element of spherical wave is established based on the 3D precise geometric relationship of the single-bounce concentric-cylinders scattering. Second, a birth-and-death model for the non-stationary characteristics in the massive MIMO array direction is developed. The channel statistical characteristic function of the proposed model is derived, and the theoretical deduction is verified by comparing the results of the characteristic function theory value and Monte Carlo statistics value. In addition, the differences of spatial correlation between the proposed model and the traditional ground-air 3D MIMO channel model based on plane wave are analyzed and compared by simulation. The simulation results show that the two models have almost no difference under the near field. And there are differences between the two models under the far field, the traditional model is no longer applicable. Finally, the simulation results of several channel characterizations and the actual test data of open literatures for ground-air channel are compared and analyzed. The results show that, as a general applicability model, the parameters of proposed model can be optimized according to the test conditions, test environment and test results of the channel in order to approach the actual channel to accurately model the specific channel.
