Abstract(in English) | This paper describes a novel method for estimating the frequency, amplitude, and phase of a real sinusoid from their mixture. We start from the characteristic differential equation and arrive newly at an exact and direct algorithm from a finite duration observation of the signal. It inherently involves the finite 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. In multi-sinusoid conditions, we show without loss of exactness some extended algorithms that can reduce the intereference between the adjacent sinusoids. |
