Abstract:
In many real time applications, time delay estimation requires a special solution. Despite the various approaches, which were proposed over the years, the topic remains hot for digital signal processing because of its large field of applications and implementation forms. Among different classes of methods for this issue, general cross-correlation method is wildly used. It offers good results and does not need an adaptation time, like those based on adaptive filtering. In this paper, we make a survey and compare the most popular generalized cross-correlation methods. We extend the analysis, by applying the accumulation of cross-power spectrum technique, for all well known generalized cross-correlation methods. The comparisons are provided by detailed numerical and simulation analysis, using several metrics. Based on the accuracy rate, error rate, standard deviation of relative error and computing time we provide new considerations for traditional generalized cross-correlation methods.
