Title:
INTELLIGENT ANTENNA CHANNEL CALIBRATION METHOD AND CALIBRATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/145534
Kind Code:
A1
Abstract:
Disclosed in the present invention are an intelligent antenna channel calibration method and a calibration device. The device comprises a first chip, and a second chip. One end of the first chip is communicated with a number N of channels of an intelligent antenna and a calibration channel by means of a change-over switch; the other end of the first chip is communicated with the second chip; the first chip receives a calibration command to sequentially collect a calibration training sequence transmitted by each channel in the N channels; the first chip transmits the collected calibration training sequences to the second chip; the second chip determines the effectiveness of the channels corresponding to the calibration training sequences; the second chip determines a calibration reference channel from the effective channels; the second chip determines, according to a preconfigured calibration index and the calibration reference channel, for each channel of the effective channels, excluding the calibration reference channel, calibration factors corresponding to the channels, and sends same to the first chip. The technical solution disclosed in the embodiment of the present invention can accelerate the processing speed in calibrating the channels and improve the accuracy of the channel calibration.
