W pracy pokazano, jak dzięki odpowiedniemu wyborowi długości odcinka realizacji (obserwacji) dyskretnego stacjonarnego procesu stochastycznego można istotnie poprawić dokładność estymacji parametrów sinusoid w nim zawartych. Wybór ten oparto o nowy, tu zdefiniowany parametr nazwany indeksem widmowej koncentracji energii periodogramu. Rozważania zilustrowano wynikami eksperymentu numerycznego.In this paper, it has been demonstrated that if the length of the discrete-time stationary stochastic process observation length is carefully selected, the accuracy of sinusoidal components parameters estimation can be significantly improved. Observation length selection is based on new, defined in this paper, parameter called spectral energy concentrat...
