Title:
LOCAL OSCILLATOR LEAKAGE CALIBRATION METHOD AND APPARATUS, ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/103976
Kind Code:
A1
Abstract:
Disclosed in the present application are a local oscillator leakage calibration method and apparatus, an electronic device and a storage medium. The local oscillator leakage calibration method comprises: obtaining a feedback signal of a transmitting signal (101), wherein the transmitting signal is obtained by converting a service signal and a pre-input special sequence signal, and the pre-input special sequence signal is a special sequence signal generated by the longest linear shift register sequence; determining a channel parameter of the service signal by means of the feedback signal and the special sequence signal (102); obtaining a local oscillator leakage value of the service signal according to the channel parameter (103); and calibrating the service signal according to the local oscillator leakage value (104).
