Characteristic reproduction method and device of MIMO OTA 3D channel space

The invention provides a characteristic reproduction method and device of an MIMO OTA 3D channel space, and belongs to the technical field of communication. The method comprises that an initial attribute vector of each individual in a preset evolution algorithm is obtained; according to the initial attribute vector of each individual, the preset evolution algorithm and a pre-stored correlation vector, which is a correlation vector of a practical channel space to be simulated, of a target channel space, a global optimal fitness and an optimal attribute vector, which is an attribute vector when the global optimal fitness is satisfied, corresponding to the global optimal fitness are determined, and according to the optimal attribute vector, position vectors and power weights of probes are determined, and a 3D channel probe model is determined on the basis of the position vectors and power weights of the probes. Thus, the test cost can be reduced.
