A signal distortion compensating apparatus and method in a digital TV translator are provided that extract a reference signal from a modulator output of a digital TV translator, and conduct a pre-correction based on the extracted reference signal to compensate for a signal distortion involved in the digital TV translator. The compensating apparatus can include a modulator that modulates an input signal while conducting a distortion pre-correction controlled by a control signal applied thereto on the input signal. The modulator outputs baseband signals divided from the input signal. A signal processing unit processes the signals outputted from the modulator, and transmits the resultant signal to subscribers. An auto correction unit compares the signal, which is outputted in a distorted state from the signal processing unit, with a reference signal derived from the baseband signals output by the modulator, and generates the control signal based on the result of the comparison.
