Provided is a mobile terminal of a wireless communication system, and more particularly, a channel estimation method performed in a mobile terminal of a wireless communication system supporting the IEEE 802.16e standard and a channel estimator of the mobile terminal to which the method is applied. The channel estimation method includes the steps of: extracting a preamble included in a received signal and obtaining a preamble estimation value based on the preamble; extracting a pilot included in the received signal and obtaining a pilot estimation value based on the pilot; and obtaining a channel estimation value based on calculating the preamble estimation value and the pilot estimation value according to a predetermined algorithm.
