Title:
TIME DELAY CALIBRATION METHOD, WIRELESS RADIO FREQUENCY DEVICE AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/120709
Kind Code:
A1
Abstract:
A time delay calibration method, a wireless radio frequency device and a computer readable storage medium. The method comprises: receiving an input signal; performing time delay adjustment on an envelope of the input signal and the input signal to obtain a change relationship of a target parameter value of an intermodulation signal of a channel adjacent to the input signal and a time delay deviation value, the time delay deviation value being a time delay of the envelope of the input signal with respect to the input signal; and determining a calibration time delay value based on the change relationship of the target parameter value of the intermodulation signal of the channel adjacent to the input signal and the time delay deviation value, to perform time delay calibration on a signal to be sent. By applying the scheme, the transportability of the method for carrying out time delay calibration on the ET can be improved.
