    摘要: The disclosure relates to a cancellation device for cancelling interference caused by a non-linear device, the cancellation device comprising: an adaptive filter coupled in parallel to the non-linear device, wherein the adaptive filter is configured to filter an input signal of the non-linear device to generate an approximation signal approximating an output signal of the non-linear device; an error signal generator configured to generate an error signal based on a function of the output signal and the approximation signal; and a controller configured to adjust the adaptive filter based on the error signal and a phase and magnitude relation of the output signal and the input signal.
