The embodiments of the present invention provide a self-adaptive narrow band interference cancellation method and apparatus. The reception apparatus in the present invention includes: a channel type determination module for measuring the time delay extension of the multi-path channel experienced by the received time-domain signal, and determining the channel type on the basis of the measurement results; a weighting coefficient selection module for selecting weighting coefficient according to the channel type; a time domain windowing processing module for performing processing of the time domain windowing for the time-domain signal according to the weighting coefficient; a frequency domain interference cancellation processing module for performing, according to the weighting coefficient, cancellation processing of frequency domain interference on the signal output after the time-domain windowed processing to cancel the narrow band interference to the time-domain signal. The embodiments of the present invention solve the problem of the existing narrow band interference method with high complication low flexibility and difficult implementation. |
