Interference cancellation method, medium, and device

A non-transitory computer-readable storage medium, wherein instructions are stored on the non-transitory computer-readable storage medium to make a computer perform an interference cancellation method, the interference cancellation method applied to an electronic device including first-type and second-type channels having signal reception function, comprising:

• collecting, from the first-type channels, a measurement signal in which an effective signal and a first interference signal are mixed, and collecting a second interference signal from the second-type channels;
• estimating the first interference signal in the measurement signal according to a coupling relationship between a first calibration data and a second calibration data and based on the second interference signal;
• and
• removing the first interference signal from the measurement signal to obtain a target effective signal;
• wherein the first calibration data and the second calibration data are interference signals collected from the first-type channels and the second-type channels respectively when the electronic device is in a preset state,
