Title:
MULTI-ANTENNA COMPENSATION METHOD AND APPARATUS THEREFOR, RADIO FREQUENCY DEVICE AND COMPUTER STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/041266
Kind Code:
A1
Abstract:
The present disclosure relates to a multi-antenna compensation method and an apparatus therefor, a radio frequency device and a computer storage medium. By acquiring an amplitude ratio and a phase difference of a coupled antenna signal, and according to the acquired amplitude ratio and phase difference, calculating an amplitude-phase variation weight value between the antenna signal and a standard antenna signal, and according to the weight value, performing amplitude-phase compensation on the coupled antenna signal, the obtained amplitude-phase of the coupled antenna signal is consistent with that of the standard antenna signal. Since an amplitude ratio and a phase difference between a coupled antenna signal and a standard antenna signal are acquired, the detected amplitude and phase difference of the antenna signal are associated with an actual length of each antenna coupling loop, so that the accuracy of calibration is greatly improved when performing antenna calibration, amplitude-phase errors of the coupled antenna signal and an original antenna signal are reduced, and the level of user experience degree when a user uses a radio frequency device is also improved at the same time.
