Abstract

The invention provides a large-scale antenna adjusting and testing method, testing equipment and computer equipment. The adjusting and testing method comprises the following steps: acquiring amplitude and phase information of each port of a first sub-array and a second sub-array of a large-scale antenna; judging whether the amplitude and the phase of each sub-array are qualified or not; calculating amplitude and phase information after any first sub-array and any second sub-array which need to be adjusted and tested are combined through computer equipment to obtain all qualified matching data; adopting a preset matching algorithm to obtain an optimal matching relationship among the sub-arrays, and generating a matching information base; and assembling according to the information of the matching relation library. The invention further provides large-scale antenna adjusting and testing equipment and computer equipment. The large-scale antenna adjusting and testing equipment comprises a multi-channel matrix switch, a network analyzer, computer hardware and an application program. According to the method, the product amplitude and phase information are stored, the combination relation of the sub-arrays is determined through the preset matching algorithm, production is arranged through an informatization means, the adjusting and testing workload is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a large-scale antenna commissioning method, testing equipment and computer equipment. Background technique [0002] In 5G and future 6G base stations, most of them use large-scale antennas, that is, Massive antennas, which integrate the radio frequency part and the antenna part in the AAU (Active Antenna Unit, active antenna processing unit). The AAU controls the antenna array The amplitude and phase difference of the antenna array elements in each channel are used to realize the beamforming of the signal, so as to improve the gain transmission in a directional way, which can greatly improve the spectral efficiency of the cell, and improve the capacity and coverage. [0003] Specifically, the influence of factors such as the welding process and assembly error of the antenna will increase the amplitude and phase difference between the ports in the antenna array, so ...
