Modeling method and modeling device applicable to three-dimensional propagation channels

The invention discloses a modeling method and a modeling device applicable to three-dimensional propagation channels. The method and the device are designed in order to solve the problem that angles in the vertical direction are neglected in existing three-dimensional propagation channel modeling. The modeling method includes the steps: firstly, acquiring a collineation connection line direction of a base station end and a mobile communication end, and working out a line-of-sight propagation angle theta according to height difference and horizontal distance between the base station end and an antenna at the mobile communication end; secondly, respectively constructing central angles theta of the base station end and the mobile communication end; and thirdly, translating a randomly-generated zero-mean elevation power angle spectrum of a three-dimensional propagation channel onto the central angles so as to obtain zero-mean elevation power angle spectrums of the base station end and the mobile communication end respectively. The method and the device are simple and feasible to implement, high in practicality and capable of making up deficiencies of modeling at elevation angles in the prior art.
