METHOD AND AN APPARATUS FOR ESTIMATING A CHANNEL USING DATA CHANNEL, PARTICULARLY FOR HAVING HIGH CHANNEL ESTIMATION FUNCTION REGARDLESS OF A WIRELESS CHANNEL ENVIRONMENT

摘要

PURPOSE: A method and an apparatus for estimating a channel using data channel are provided to control the reflection ratio of a data channel estimation value.;CONSTITUTION: A channel value extracting unit(210) extracts a first estimation value from a pilot reception signal received through a pilot channel and a second estimation value from a data reception signal received through a data channel. A gain adjustment unit(220) adjusts the gain of the second estimation value by using the weight value calculated in the weight calculation value. A channel estimation unit(240) estimates a final value from the first and second estimation values.;COPYRIGHT KIPO 2010
