Ankunftszeit, Amplitude, Phase,...) hätte, dann würde dem Neyman-Pearson-Lemma zufolge das Optimalfilter (bei Gaußschem Rauschen) die Fehlerwahrscheinlichkeit minimieren.
WebA very popular form of hypothesis test is the likelihood ratio test, which is a generalization of the optimal test for simple null and alternative hypotheses that was developed by Neyman and Pearson (We skipped Neyman-Pearson lemma because we are short of time). http://parker.ad.siu.edu/Olive/ich7.pdf
WebAccording to the Neyman Pearson lemma, we can create the most powerful test by looking at the likelihood ratio (LR). I simplified the LR and got the following which I believe is correct, hopefully! L R = e − n μ a + n μ 0 ( μ a μ 0) ∑ i = 1 n y i
WebNext, similar to , Neyman–Pearson lemma removes the stacked signals r i that most likely contain only background noise with low SNR. After concatenating the remaining consecutive windows, we form new windows W ˜ j. For example, suppose that W 1, W 2, W 3, W 5, and W 6 are the remaining windows after Neyman–Pearson lemma. bywood schoolWebThe Neyman–Pearson lemma provides a method for constructing most powerful tests for simple hypotheses.
