AbstractIn this paper, an adaptive notch filter is investigated for eliminating sinusoids imbedded in noise. The algorithm estimates the sinusoidal frequencies directly from data samples to avoid the variation caused by small perturbation in the estimated coefficients of the filter. And then the notch filter is designed in terms of the estimated frequencies. The stability of the adaptive notch filter can always be ensured without any stability monitoring during adaptive processing. It converges rapidly and attains the Cramer-Rao bound (CRB) for a sufficient large data set. Simulation results are included to demonstrate the performance of the algorithm. © 1992.
