Abstract

A method and apparatus for performing channel estimation in an Orthogonal Frequency Division Multiplexing (OFDM) wireless communication system. The method and apparatus includes receiving a training sequence at each of a plurality of predetermined subcarriers; performing primary channel estimation on each of the training sequences by a Least Square (LS) algorithm; grouping the subcarriers into a predetermined number of subgroups, and acquiring a linear filter coefficient for each of the subgroups based on a channel estimate acquired for each of the subcarriers by the primary channel estimation; and performing secondary channel estimation on each of the subcarriers by performing a Minimum Mean-Square Error (MMSE) algorithm based on the linear filter coefficient of each subgroup.
