The present invention relates to a method for estimating a channel in a wireless communication system. In the method, a reference value is generated on the basis of a value indicating a non-Gaussian characteristic of an inter-cell interference signal and power values of received pilot symbols, the reference value is compared with each of the power values of the pilot symbols, at least one pilot symbol, which is relatively lightly damaged by the inter-cell interference signal, is selected, and a channel is estimated using the at least one selected pilot symbol.
