<p>The present invention discloses a method for removing narrowband interference and an adaptive filter, and includes: the adaptive filter determines a weight value corresponding to the current sampling instant; the adaptive filter, according to the determined weight value and a reference signal sampled at the current sampling instant, determines an estimated waveform of a time domain waveform of an interference signal corresponding to the current sampling instant; the adaptive filter, according to the determined estimated waveform of the time domain waveform of the interference signal, performs filtering on a baseband signal sampled at the current sampling instant, and obtains the baseband signal with narrowband interference removal. With the present invention, the processing time delay for interference cancellation can be reduced, the real-time performance can be enhanced, and the interference cancellation effect can be improved.</p> |
