Time Delay Estimator Based on Frequency Estimation Approach
نویسندگان
چکیده
In this Letter, the problem of estimating the timedifference-of-arrival between signals received at two spatially separated sensors is addressed. By taking discrete Fourier transform of the sensor outputs, time delay estimation corresponds to finding the frequency of a noisy sinusoid with time-varying amplitude. The generalized weighted linear predictor is utilized to estimate the time delay and it is shown that its estimation accuracy attains Cramér-Rao lower bound. key words: time delay estimation, frequency estimation

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 ...

A new Markov-based method for real time prediction of network transmission time delays is introduced. The method considers a Multi-Layer Perceptron (MLP) neural model for the transmission network, where the number of neurons in the input layer is minimized so that the required calculations are reduced and the method can be implemented in the real-time. For this purpose, the Markov process order...
متن کاملAdaptive Technique for Computationally Efficient Time Delay and Magnitude Estimation of Sinusoidal Signals
— An online, adaptive method of time delay and magnitude estimation for sinusoidal signals is presented. The method is based on an adaptive gradient descent algorithm that directly determines the time delay and magnitudes of two noisy sinusoidal signals. The new estimator uses a novel quadrature carrier generator to produce the carriers for an adaptive quadrature phase detector, which in turn u...
متن کاملAdaptive subsample time delay estimation
This letter addresses the problem of on-line subsample time delay estimation of narrowband signals of known center frequency. A new form of the Lagrange interpolator lter is presented in this letter which is incorporated into the explicit time delay estimator (ETDE) method. Simulations show that ETDE with the lter modulated to the signal center frequency signiicantly outperforms conventional ETDE.
