Title:
ANTENNA CALIBRATION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/024861
Kind Code:
A1
Abstract:
Disclosed in the present application are an antenna calibration method and device. In the method, in a receiving channel calibration process, first a receiving channel beam weight matrix is initially updated by using a receiving calibration signal from a reference beam direction, i.e., performing initial receiving channel calibration, and then, for different beam direction regions, beam weight vectors corresponding to multiple beam directions within particular beam direction regions are updated. Thus, beam weight vectors corresponding to particular regions in the receiving channel beam weight matrix are updated by region, that is, receiving channels are calibrated by region.
