Abstract	This paper proposes a technique to reduce the sample number of channel's pulse response required to optimize equalization coefficients. In our method, channel's pulse response is aliased in calculating equalization coefficients reducing the number of samples of the channel's frequency response. As a result, the computation time to acquire the channel's frequency response is greatly reduced. To demonstrate our method, equalization coefficients are calculated using the conventional and our methods and then compared. Since the necessary number of samples is reduced by 8 times at most in our method, the computation time is reduced up to by 7.01 times. For accuracy verification, we also calculated the equalized eye sizes using both methods. The calculated eye sizes are almost identical. These results show that using our method, engineers can accurately optimize equalizing transceiver design with reduced efforts to simulate channel's frequency response.
