Abstract: In this work we have applied Adapive Boosting (AdaBoost) for channel estimation of Orthogonal Frequency Division Multiplexing (OFDM) systems. The result of the AdaBoost algorithm was compared with other algorithms such Least Square (LS), Best Linear Unbiased Estimator (BLUE) and Minimum Mean Square Error (MMSE).

Keywords: OFDM; orthogonal frequency division multiplexing; channel estimation; least squares; MMSE; minimum mean square error; BLUE; best linear unbiased estimator; AdaBoost; adapive boosting.
