Subsample Time delay estimation using fractional Fourier transform
نویسندگان
چکیده
The need for subsample time delay estimation (TDE) between two signals arises quite often in many areas such as radar; sonar etc. In this paper, the use of fractional Fourier transform (FRFT) for subsample TDE is proposed. The proposed estimator uses the magnitude of the FRFT of the signals, although the phase angle of it can also be exploited for the estimation purpose. To validate the proposed approach, simulation results of the proposed estimator are also presented.

Adaptive Subsample Time Delay Estimation for Narrowband Signal Synchronisation
This paper addresses the problem of subsample or fractional sample time delay estimation of narrowband signals of known centre frequency, in order to synchronise the signals. The Lagrange interpolator filter is incorporated into the explicit time delay estimator (ETDE) method. In order to achieve this, a new form of the Lagrange interpolator is presented in this paper. Further modifications are...
متن کاملApplication of Fractional Fourier Transform in Cepstrum Analysis
Source wavelet estimation is the key in seismic signal processing for resolving subsurface structural properties. Homomorphic deconvolution using cepstrum analysis has been an effective method for wavelet estimation for decades. In general, the inverse of the Fourier transform of the logarithm of a signal’s Fourier transform is the cepstral domain representation of that signal. The convolution ...
متن کاملWindowing Effects of Short Time Fourier Transform on Wideband Array Signal Processing Using Maximum Likelihood Estimation
During the last two decades, Maximum Likelihood estimation (ML) has been used to determine Direction Of Arrival (DOA) and signals propagated by the sources, using narrowband array signals. The algorithm fails in the case of wideband signals. As an attempt by the present study to overcome the problem, the array outputs are transformed into narrowband frequency bins, using short time Fourier tran...
متن کاملAn Adaptive Subsample Delay Estimator using a Quadrature Demodulator
An on-line delay estimation algorithm based upon an analogue quadrature phase detector that is suitable for determining the subsample delay between two noisy sinusoidal signals is introduced. The new estimator uses a discrete-time quadrature technique to directly update the delay estimate, which is in turn used to adapt the coefficients of a simple fractional delay filter (FDF). The estimator i...
متن کاملPerformance Improvement on Local Polynomial Periodogram
With the Lv’s distribution (LVD), the chirp rates of linear frequency modulated (LFM) signals can be more accurately estimated for the local polynomial periodogram (LPP). Comparing to the estimation methods based on the polynomial Fourier transform (PFT) and fractional Fourier transform (FrFT), it is shown that LPP with the chirp rate estimated by LV’s distributioneffectively obtains better per...
