Figure 2From: Preamble-based frequency-domain joint CFO and STO estimation for OQAM-based filter bank multicarrierAmplitude of a received preamble for k=0 with G=1 . The time axis has a sampling rate of M/T (with M=512 in this case), while the processed preamble symbols y0[ n M/2] (crosses in the figure) have a rate of 2/T. If an STO δ is applied, the amplitude of y0[ n M/2] will be different (circles in the figure).Back to article page
