Echo Delay Estimation Using Algorithms Based on Cross-correlation
Original language description
The paper introduces a study on correlation-based time delay estimation algorithms. Its main purpose is to suggest a number of algorithms, which are the most suitable for real-time processing of speech signals. Time delay estimation is an important topicduring transmission of voice signals over packet-switching telecommunication systems. An echo delay problem associated with IPbased transport networks is discussed in the text. An experimental comparison of the performance of several methods based on cross-correlation, normalized cross-correlation and generalized crosscorrelation to estimate the true time delay between two speech signals is presented, too.
