METHOD AND APPARATUS FOR ESTIMATING CHANNEL IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a method of estimating a channel in a wireless communication system, which is suitable in a non-Gaussian environment, and an apparatus thereof. A method of estimating a channel in a wireless communication system according to the present invention includes the following steps of: generating a reference value by using a parameter concerned with a non-Gaussian property of a cell interference signal; comparing the reference value with the powers of a plurality of pilot symbols, respectively, to sort a valid pilot symbol which is not damaged by the cell interference signal; and estimating a channel by using the sorted valid pilot symbol.
