摘要
PURPOSE: A channel estimation method and apparatus thereof are provided to promote a channel estimation performance using an L-LTF(Legacy-Long Training Field) and an HT-LTF(High Throughput Long Training Field) at the same time.;CONSTITUTION: A reception unit(505) receives reference signals(201,202,203). A first estimation unit(510) acquires estimation values of a channel based on the reference signals. A second estimation unit(520) processes DFE(Decision Feedback Equalization) based on the first estimation value and the reference signal. The second estimation unit acquires a second estimation value. An update unit(530) acquires a first update value using the weighted average of the first and the second estimation value.;COPYRIGHT KIPO 2013;[Reference numerals] (505) Reception unit; (510) First estimation unit; (520) Second estimation unit; (530) Update unit
