Figure 6From: Frequency tracking by method of least squares combined with channel estimation for OFDM over mobile wireless channelsPerformance of ML channel estimator after LS frequency offset correction. With initial frequency offset δ = 0.48 and for L = 1,3,9, shown here are MSE of ML CFR estimator versus SNR curves by Monte Carlo simulations as well as by theory. The CRB curve is for ML CFR estimator using one OFDM training block.Back to article page
