Abstract
A method and apparatus for estimating a channel in an Orthogonal Frequency Division Multiplexing (OFDM) wireless communication system. A Least-Square (LS) channel estimator receives a training sequence, and performs LS channel estimation on each of a predetermined number of subcarriers independently. A Split Minimum-Mean-Square-Error (S-MMSE) channel estimator separates the predetermined number of subcarriers into a predetermined number of groups, calculates an S-MMSE filter for a subcarrier in each group, and estimates an S-MMSE channel by applying the S-MMSE filter to each of the groups.
