Time delay estimation based on the higher-order statistics of signals

Time Delay Estimation (TDE)is a fundamental passive sonar signal processing problem. It is important in many areas such as sonar, biomedicine, radar and geophysics. Generalized Cross Correlation (GCC)method has been the conventional method of estimating time delays, but it has certain limitations on...
