Embodiment Construction
[0045] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0046] figure 1 It is a three-dimensional space multi-antenna MIMO model based on the distribution of Von Mises Fisher scatterers. The scatterers are distributed on the surface of a three-dimensional space sphere and obey the Von Mises Fisher distribution:
[0047]
[0048] where μ is the average direction vector of the scatterer cluster (||μ||=1), in polar coordinates
[0049] θ 0 and are the average arrival azimuth angle and average arrival elevation angle of the scatterer cluster, k is the expansion factor of the scatterer cluster around μ, and k≥0.
[0050] The wireless channel model ...
