摘要
Complex signal samples of an input signal are supplied to via a frequency down-shifter to a digital filter, and to a time-frequency transform unit which produces a plurality of frequency components each associated with a respective frequency band within a bandwidth of the input signal. The frequency component having the maximum momentary energy is determined to determine the down-shifting frequency for the associated frequency band to be filtered, and to determine a complementary up-shifting following the digital filter to produce an output signal. The filter can be a bandpass filter or a bandstop filter, especially for reducing co-channel interference in different types of wireless communications systems.
