Adaptive Subsample Time Delay Estimation for Narrowband Signal Synchronisation
نویسندگان
چکیده
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 made to the ETDE algorithm. Simulations show delay estimation bias using the new algorithm is orders of magnitude smaller than conventional “sinc”-based ETDE.

Adaptive 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.
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 کاملComparison of Discrete Subsample Time Delay Estimation Methods Applied to Narrowband Signals
The problem of estimating the subsample time delay between two noise-corrupted narrowband signals is considered. Signiicant improvements to two previously proposed estimators, the MXS and MSX, are made. The performance of the revised estimators are assessed through simulation over a range from-10 to 20 dBs, with four well-known estimators, two of which are asymptotically maximum likelihood (the...
متن کاملTime Delay Compensation for Adaptive Multichannel Speech Enhancement Systems
Several algorithms for adaptive multichannel speech enhancement have been tested in an office room and in an anechoic chamber using different noise sources. Temporal synchronisation requires time delay estimation and compensation of the desired speech signal received at different sensors.
