Embodiment Construction
[0035] At present, the time delay calibration method for ET is almost entirely dependent on the implementation of hardware circuits. Since different hardware circuits and different radio frequency devices have different time delays, the portability of the above method is poor.
[0036] For this reason, the embodiment of the present invention provides a time delay calibration method. In the method, by adjusting the time delay of the envelope of the input signal and the input signal itself, the intermodulation signal of the channel adjacent to the input signal is obtained. The variation relationship between the target parameter value and the delay deviation value, and then the calibration delay value can be determined based on the variation relationship between the target parameter value and the delay deviation value of the intermodulation signal of the channel adjacent to the input signal. The above solution is less dependent on the hardware circuit, so the portability is strong...

A time delay calibration method, radio frequency equipment and computer-readable storage medium. The method includes: receiving an input signal; performing delay adjustment on the envelope of the input signal and the input signal itself, to obtain the target parameter value of the intermodulation signal of the channel adjacent to the input signal and the delay deviation value Variation relationship; the delay deviation value is the time delay of the envelope of the input signal relative to the input signal; the change relationship between the target parameter value and the delay deviation value based on the intermodulation signal of the adjacent channel of the input signal , to determine the calibration delay value, so as to perform delay calibration on the signal to be sent. By applying the above solution, the portability of the method for performing time delay calibration on ET can be improved.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a time delay calibration method, wireless radio frequency equipment and a computer-readable storage medium. Background technique [0002] In a wireless radio frequency device, a power amplifier (Power Amplifier, PA) is usually provided to amplify an input signal, so as to improve the transmission performance of the wireless radio frequency device. The working efficiency of the PA is related to its power supply voltage. [0003] In practical applications, either a fixed voltage can be provided for the PA as the power supply voltage, or a variable voltage can be provided for the PA as the power supply voltage. Compared with a fixed power supply voltage, a variable power supply voltage can more effectively improve the working efficiency of the PA. [0004] At present, a variable power supply voltage is provided for the PA mainly through an envelope tracking (Envolope Trackin...
