Abstract
Exemplary embodiments of the present invention relate to a method of estimating a channel in a wireless communication network using the IEEE 802.11ad communication standard, and more particularly, to a method of estimating a channel which can determine a channel environment and actively select a channel estimation scheme according to the determined channel environment, and correctly estimate the channel while reducing the amount of computation by selectively using a pilot channel estimation value only in a pilot estimation period and adjacent pilot estimation periods when the channel changes severely, i.e., when a deep hole occurs, in the pilot estimation period although an LTF channel estimation value is used.
