Disclosed is a digital direct conversion receiver including a clock generation and a distribution unit to generate a clock signal having a time difference that generates a predetermined phase difference, a Track & Holder (T&H) to perform sampling of a radio frequency (RF) signal selected by a tunable RF filter with a selected sampling frequency and down converting of the sampled signal, and to generate the predetermined phase difference between sampled signals by using the clock signal having the time difference during the down-conversion, an analog-digital (AD) converter to generate a sample stream having phase difference information from the down-converted sampled signal, and a complex interpolant to eliminate an image component from the sample stream using a phase difference between a plurality of sample streams.
