Abstract(in English) | This paper describes a novel method for estimating the frequency, amplitude, and phase of a real sinusoid from finite length discrete samples. We start from the characteristic difference equation and arrive newly at an exact and direct algorithm based on a discrete version of the weighted integral method. It involves the discrete Fourier transform, thus multiple sinusoids can be decomposed and estimated independently and accurately. In noisy conditions, we compare the estimation error covariance with the Cramer-Rao lower bound. We show several experiments using real signals with rich time-frequency structures. |
