Abstract
When estimating time-delays of signals from sensor outputs, the bispectrum has advantages when the signal has a skewed distribution. The authors provide nonparametric estimation approaches which exploit the two-dimensional nature of the bispectrum. When dealing with observations from more than a pair of sensors, the new algorithms have computational advantages and, in some cases, show improved performance compared to the conventional nonparametric, bispectrum-based time-delay estimation approachKeywords
