Abstract :
This paper is concerned with the estimation of frequencies of sinusoids based on the data disturbed by fractal noises. For fractionally differenced Gaussian noises, a combinatory method of bias compensated least squares (BCLS) and maximum likelihood (ML) is presented here for this problem. It is demonstrated by simulations that the new approach has high resolution and can suppress the effect of fractionally differenced Gaussian noise.
