(Color online) Performance comparison in terms of RMSE of the adaptive KF scheme against the best individual estimation algorithm (ndf for synthetic signals and swipe for actual signals). All error units are in Hz. For the majority of signals used in this study, the adaptive KF scheme is superior to the single best estimation algorithm, in some cases considerably so. In two cases for the synthetic signals and two cases for the actual signals the RMSE difference is larger than −15 Hz.
