A Novel Scheme for Time Delay Estimation in the Fractional Fourier Transform Domain
Xue Mei Li · Applied Mechanics and Materials · 2013
A time delay estimator based on the fractional bispectrum is proposed; and it is suitable for the chirp signal. The proposed time delay estimation technique can outperform the conventional time delay estimation methods associated with the bispectrum in the Fourier domain under the correlated Gaussian noises at lower SNR. Simulation results demonstrate the validity of this estimation method.
