Title:
SIGNAL PROCESSING METHOD AND RELATED APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/077921
Kind Code:
A1
Abstract:
Provided are a signal processing method and a related apparatus, wherein same are used for determining a shaft alignment state between a receiving end and a sending end at a lower complexity. The method of the embodiments of the present application comprises: after a sending end sends OAM signals to a receiving end, the receiving end determining a first phase difference between a first received signal and a second received signal, and a second phase difference between the second received signal and a third received signal, wherein the first received signal is an OAM signal received by a first antenna in the receiving end, the second received signal is an OAM signal received by a second antenna in the receiving end, and the third received signal is an OAM signal received by a third antenna in the receiving end; and if the difference between the first phase difference and the second phase difference determined by the receiving end is less than or equal to a calibration threshold value, determining that a state between the receiving end and the sending end is a shaft alignment state.
