Estimation algorithm for higher order spectral of time delay esthnation
Sun Ying · Journal of Changchun University · 2003
The estimation methods for higher order spectral are efficient in estimating time delay in colored noise. This paper introduces the higher order moment estimation algorithm under the correlated Gaussian colored noise, avoids soluting unknown spatially additive noises using the cross spetral estimation. Simulations have shown that this method can prohibit the colored noise and basically estimate the location of time delay under signal-to-noise ratio-2.5dB.
