Figure 4From: Frequency tracking by method of least squares combined with channel estimation for OFDM over mobile wireless channelsPerformance of frequency tracking by method of least squares using L + 1 OFDM training blocks. With initial frequency offset δ = 0.48 and for L = 1,3,9, shown here are MSE of frequency offset estimator versus SNR curves by Monte Carlo simulations as well as by theory. The CRB curve is for ML frequency estimator using one OFDM training block.Back to article page
