Abstract

Embodiments of the present invention provide a method and device for reproducing MIMO OTA three-dimensional channel space characteristics, which belong to the field of communication technology. The method includes: obtaining the initial attribute vector of each individual in the preset evolutionary algorithm; according to the initial attribute vector of each individual, the preset evolutionary algorithm and the pre-stored correlation vector of the target channel space, determine The global optimal fitness and the optimal attribute vector corresponding to the global optimal fitness, wherein the correlation vector of the target channel space is the correlation vector of the actual channel space to be simulated, and the optimal attribute vector is The attribute vector when the global optimal fitness is satisfied; according to the optimal attribute vector, determine the probe position vector and the power weight of each probe, and determine the three-dimensional channel probe based on the probe position vector and the power weight of each probe Model. By adopting the invention, the test cost can be reduced.

Description

Technical field [0001] The present invention relates to the field of communication technology, and more particularly to a method and apparatus for reproducing a MIMO OTA 3D channel spatial characteristic. Background technique [0002] With the development of communication technology, the applications of multiple-input multiple-outprut, mimo technology are more widely used. MIMO technology, by air coding, using non-correlation in the propagation channel, can improve the channel capacity of the communication system while not additional spectral and time domain resources, and improves the data transmission rate. [0003] In order to effectively assess the performance of the MIMO device of the wireless communication system in a real environment, researchers have proposed multiple air-input multiple-outprut over-air, mimo ota tests for MULTILE-IN AIR, MIMO OTA. The MIMO OTA test scheme can create a channel space to simulate the real environment around the measured MIMO device, which c...
