Time-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 کاملTime Delay Estimation via Multichannel Cross-correlation
Time delay estimation (TDE) in a reverberant acoustical environment is a very challenging and difficult problem. This paper tackles the problem by exploiting the redundant information provided by multiple microphone sensors. To do so, the multichannel crosscorrelation coefficient (MCCC) is re-derived, in a new way, to connect it to the well-known linear interpolation technique. Some interesting...
متن کاملOn the application of cross correlation function to subsample discrete time delay estimation
Cross correlation function (CCF) of signals is an important tool of multi-sensors signal processing. Parabola functions are commonly used as parametric models of the CCF in time delay estimation. The parameters are determined by fitting samples near the maximum of the CCF to a parabola function. In this paper we analyze the CCF for the stationary processes of exponential autocorrelation functio...
متن کاملTime 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 کاملPerformance Evaluation of Cross Correlation Based Node Estimation Technique
Estimating the number of operating nodes is an important factor in wireless communication network (WCN) in which the nodes are deployed in different forms to cover small or large areas of interest for a wide range of personal, scientific and commercial applications. It is important to estimate the number of operating nodes at any point in time for proper network operation and maintenance. Prope...
