The present invention provides an apparatus for channel equalization and method thereof, by which a digital signal received via a plurality of antennas is equalized. The present invention includes receiving digital transmission signals using a plurality of antennas, respectively, initializing equalizer coefficients and equalizing the received signals respectively, adding the equalized signals together, predicting a noise amplified in the equalizing step, and generating a final output signal by removing the predicted noise from a value resulting from adding the equalized signals together. Therefore, the present invention performs equalization using a plurality of antennas, thereby enhancing the signal to noise ratio of the final output and facilitating the equalization of the severely distorted channel.
