Embodiment Construction
[0042] Such as Figure 6 As shown, the present invention provides a 3DMIMO channel modeling method. There are three reference coordinate systems in the 3DMIMO channel model, and the statistical correlation between the coordinate systems is represented by the relative rotation angle of the coordinate axes. The electromagnetic wave propagation direction considered in the modeling is in the GCS coordinate system, while the pattern representation of the antenna is relative to the ECS. According to the mutual conversion relationship between the coordinate systems, the normalized horizontal polarization vector of the electromagnetic wave in the ECS coordinate system can be calculated and the vertical polarization vector
[0043] Since the scatterer is moving during modeling, a drop of the channel is defined first. In a drop, all parameters are fixed except the phase of the sub-path. Thus, the movement within a decimation can be considered virtual, causing fast fading and Dopple...
