Estimation of Scintillation Indices: A Novel Approach Based on Local Kernel Regression Methods
Figure 9
(a) shows the correlation between the Butterworth sixth-order filter and the IIR filter. (b) shows the correlation between the Butterworth sixth-order filter and an advanced nonparametric regression with kernel smoothing. Finally, (c) shows the correlation between the Butterworth sixth-order filter and nonparametric regression. The plots show high correlation between filtering algorithms, up to 83.4% for rad.
