摘要

In many applied problems, one makes use of the time series (or stochastic process) y(t) = x(t) + e(t), where x(t) is a deterministic periodic function of the time t, that is, x(t) = x(t + T), whose minimal period is equal to T, where T is the period length (the minimal possible), and e(t) is the random "noise" that distorts the periodical signal. We have to estimate the period length T and the periodic component x(t). The function x(t) is not thought of as belonging to some parametric family, that is, we are in the context of the problem of nonparametric estimation of the (minimal) period length and the periodic component of a signal.
