摘要：

In this paper the problem of estimating the difference in arrival times of non-Gaussian signals at two spatially separated sensors is considered. It is assumed that the signals were corrupted by uncorrelated white Gaussian noises or by colored Gaussian noises. Some synthetic signals were generated and a real voice signal was recorded in an acoustic anechoic chamber. Based on these signals some methods for time delay estimation were tested.
