摘要： Method for estimation of at least one signal of interest (s
1 (t), s
1 (n)) from at least one discrete- time signal (y(n)), said method comprising the steps of a) transforming the at least one discrete-time signal (y(n)) into a frequency domain to obtain a complex spectrum (I) of the at least one discrete-time signal (y(n)); b) performing a phase-unaware amplitude estimation on the complex spectrum (I) to obtain an estimated amplitude spectrum of the at least one signal of interest (s
1 (t), s
1 (n)); c) performing a phase estimation on the complex spectrum (I) said phase estimation being an amplitude-aware phase estimation using an input signal (s
in (n)) to obtain an estimated phase spectrum of the at least one signal of interest (s
1 (t), s
1 (n)), wherein the result of the amplitude estimation of the preceding step b) is used as an input signal (s
in (n)); d) performing an amplitude estimation on the complex spectrum (I) said amplitude estimation being a phase-aware amplitude estimation using the result of the phase estimation of step c) to obtain an enhanced complex spectrum (II) of the at least one signal of interest (s
1 (t), s
1 (n)).
