Problems solved by technology

However, in a three-dimensional multi-probe anechoic chamber, the incoming wave direction of the channel may come from various three-dimensional directions, and the reference measurement antenna cannot be a three-dimensional isotropic antenna
When the reference measurement antenna is not a three-dimensional isotropic antenna, the reference measurement antenna will superimpose different antenna gains on multipath signals in different incoming wave directions, which may affect the verification conclusion of the channel model and lead to the simulation effect of the three-dimensional channel in the multi-probe anechoic system misjudgment

Abstract

An embodiment of the invention provides a three-dimensional channel model spatial correlation verification method and system. According to an acquired three-dimensional radiation pattern of a reference measurement antenna in a multi-probe darkroom, a receiving antenna is determined as a spatial correlation factor between an optional pair of spatial positions of the reference measurement antenna. According to the three-dimensional channel model spatial correlation verification method and system, the influence of the three-dimensional radiation pattern of the reference measurement antenna on channel verification testing results is taken into consideration, misjudgment of system channel simulation results is avoided, and three-dimensional channel model verification conclusions are more accurate.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and more specifically, to a method and system for verifying spatial correlation of a three-dimensional channel model. Background technique [0002] At present, the channel simulation accuracy in the multi-probe anechoic chamber will directly affect the accuracy of the antenna test results, and the channel simulation accuracy in the anechoic chamber generally depends on the target channel model, the number and position of the probes in the anechoic chamber, and the multi-probe radiation signal optimization algorithm. [0003] In the actual multi-probe anechoic system, in order to verify the channel simulation effect of the multi-probe system, that is, to verify whether the channel environment in the anechoic chamber conforms to the expected model, it is necessary to use the reference measurement antenna to actually measure the channel response of different spatial l...
