摘要：

A real time scheme to track the frequencies of multiple sinusoids in a noisy waveform is proposed. The problem of estimating the frequencies is formulated as that of adapting the parameters of a notch filter so that the mean-squared prediction error is minimized. To overcome the computational complexity, an improved adaptation scheme is proposed based on estimating one frequency at a time and is compared with other state-of-the art schemes. A prototype of the proposed scheme is constructed using a commercially available Digital Signal Processing (DSP) board.
