AI Technical Summary

Problems solved by technology

In commercial use, due to the complexity of the environment, the base station will be interfered by various external factors during the communication process. Sometimes some antenna channels are abnormal. If one channel is abnormal, the antenna calibration will not pass, and the calibration weight It cannot be compensated to the channel, which will affect the service shaping effect, and eventually lead to a great reduction in the signal quality of the user terminal

Abstract

The invention relates to an antenna correction method and device, a base station, and a computer readable storage medium. When the base station triggers antenna correction in one direction, if there is a fault channel in the direction, the fault channel is eliminated by a marking mode, the fault channel and a channel in another direction corresponding to the fault channel are specifically marked,and antenna correction in the direction is performed for normal channels other than the fault channels. Therefore, when the antenna correction in the other direction is triggered, the antenna correction only needs to be performed on the channel which is not marked in the direction, thereby avoiding the problem that the antenna system fails to correct the antenna due to a small number of antenna channel faults, and improving the performance stability of the antenna system.

Description

technical field [0001] The present invention relates to the field of mobile communication technologies, and in particular, to an antenna calibration method and device, a base station and a computer-readable storage medium. Background technique [0002] In the smart antenna system, many uncertain factors make the real antenna array manifold have array errors, which will seriously affect the performance of the baseband algorithm. The multi-antenna calibration based on the large-scale multiple-input multiple-output system is an important means to ensure the excellent performance of the antenna system. In commercial use, due to the complexity of the environment, the base station will be interfered by various external factors during the communication process, and sometimes some antenna channels are abnormal. If one channel is abnormal, the antenna calibration will fail, and the calibration weights It cannot be compensated on the channel, which will affect the service shaping eff...
