Time Delay Estimation Based On
This paper proposes a new time delay estimation model, Summary Cross-correlation Function (SCCF). It is based on a hearing model of the human ear, which comes from a pitch perception model. The inherent relation between some time delay estimation (TDE) and pitch perception method is mentioned, and propose an idea some pitch perception models’ pre-processing can be used for references in TDE mod...
متن کاملTime-Delay Estimation Based on Multilayer Correlation
Time-delay estimation technique is a key to acoustic temperature field measurement. In order to acquire a stable acoustic time-of-flight in low SNR, a time-delay estimation method combined multilayer cross-correlation and multilayer auto-correlation (MC method for short) is proposed. Crosscorrelation method and second correlation method are described briefly for comparison. Theory analysis and ...
متن کاملApplication of Model-Based Estimation to Time-Delay Estimation of Ultrasonic Testing Signals
Time-Delay-Estimation (TDE) has been a topic of interest in many applications in the past few decades. The emphasis of this work is on the application of model-based estimation (MBE) for TDE of ultrasonic signals used in ultrasonic thickness gaging. Ultrasonic thickness gaging is based on precise measurement of the time difference between successive echoes which reflect back from the back wall ...
متن کاملReal-Time Delay Estimation Based on Delay History
Motivated by interest in making delay announcements to arriving customers who must wait in call centers and related service systems, we study the performance of alternative real-time delay estimators for the delay before entering service of an arriving customer based on recent customer delay experience. We characterize performance by the bias and the mean squared error (MSE) We do analysis and ...
متن کاملEmpirical mode decomposition based time-frequency attributes
This paper describes a new technique, called the empirical mode decomposition (EMD), that allows the decomposition of one-dimensional signals into intrinsic oscillatory modes. The components, called intrinsic mode functions (IMFs), allow the calculation of a meaningful multicomponent instantaneous frequency. Applied to a seismic trace, the EMD allows us to study the di erent intrinsic oscillato...
