Application of Fourth-Order Statistics in the Time Delay Estimation
Lin Xiang-ping · Radar & Ecm · 2002
It is required to estimate the time delay of signals in the Gaussian noise surroundings in the practical location. The time delay estimation (TDE) method based on cross-correlation and cross-power spectra is sensitive to noise. The TDE method based on fourth-order statistics is discussed in this paper and several approaches to find the time delay are given, which can efficiently solve the problem that traditional methods cannot do.
