Computationally Efficient Algorithm for Estimating the Frequency of Signals at the Output of a Channel with White Gaussian Noise and Narrowband Interference

—A computationally efficient algorithm is proposed for estimating the frequency of a quasi-harmonic signal in the presence of narrowband interference based on iterative calculation of the autocorrelation sequence. A feature of the algorithm is the use of an additional filtering procedure that improv...

Summary:—A computationally efficient algorithm is proposed for estimating the frequency of a quasi-harmonic signal in the presence of narrowband interference based on iterative calculation of the autocorrelation sequence. A feature of the algorithm is the use of an additional filtering procedure that improves its stability. Simulation results have confirmed the proximity of the estimates obtained to the theoretical boundaries.
