Title:
SIGNAL INTERFERENCE CANCELLATION METHOD AND APPARATUS, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/131029
Kind Code:
A1
Abstract:
Embodiments of the present application disclose a signal interference cancellation method and apparatus, and an electronic device. The method comprises: obtain first sample data of a transmitted signal and second sample data of a received signal (S1000); obtaining an interference cancellation parameter according to the first sample data and the second sample data, the interference cancellation parameter comprising a transmission channel filter coefficient, a nonlinear model coefficient, and a receiving channel filter coefficient (S2000); sequentially performing transmission channel filtering, nonlinear transformation and receiving channel filtering on the transmitted signal according to the interference cancellation parameter so as to obtain a cancellation signal (S3000); and generating, according to the cancellation signal and the received signal, an output signal capable of canceling passive intermodulation interference (S4000).
