SELF-ADAPTIVE NARROW BAND INTERFERENCE CANCELLATION METHOD AND APPARATUS

摘要

Embodiments of the present invention provide an adaptive narrowband interference cancellation method and an apparatus. A receiving apparatus in the present invention includes: a channel type determining module, configured to: measure a delay spread of a multipath channel passed by a received time-domain signal, and determine a channel type according to a measurement resu a weighting coefficient selection module, configured to select a weighting coefficient according to the channel type; a time-domain windowing processing module, configured to perform time-domain windowing processing on the time-domain signal according to the weighting coefficient; and a frequency-domain interference cancellation processing module, configured to perform, according to the weighting coefficient, frequency-domain interference cancellation processing on the signal that is output after the time-domain windowing processing, so as to cancel narrowband interference of the time-domain signal. The embodiments of the present invention resolve a problem that an existing narrowband interference method is relatively complex, less flexible, and difficult to implement.
