发明名称 Apparatus and method of time delay estimation
摘要 An apparatus and method for estimating a time delay between two signals are provided. An original signal and a delayed signal are provided to an average magnitude difference processor for determining an average magnitude difference for a sum of samples representing an envelope of each of the respective original and delayed signals, each for a series of sample delays. The time delay between the two signals is determined as the sample delay which minimizes the average magnitude difference.
