Abstract
A circuit for removing interference in a digital communications system includes: a signal processing unit for receiving a given signal and limiting the band of the signal, thereby distributing the signal to be outputted; a local oscillator for producing a carrier wave signal to be outputted; a signal mixer for receiving the signal outputted from the processing unit and the carrier wave signal outputted from the local oscillator and mixing the two signals for output; an A/D converter for receiving the mixed signal outputted from the signal mixer and converting the mixed signal into a digital signal to be outputted; an equalizer for receiving the converted signal outputted from said A/D converter and compensating for distortion of the converted signal to be outputted; and a signal restoring unit for receiving the distortion-compensated signal outputted from the equalizer, detecting the phase of the distortion-compensated signal and restoring the signal to an original signal.
