Efficient super resolution time delay estimation techniques
In this paper, an e cient Weighted Fourier transform and RELAXation based algorithm (referred to as WRELAX) is rst proposed for the well-known time delay estimation problem. WRELAX involves only a sequence of weighted Fourier transforms. Its resolution is much higher than that of the conventional matched lter approach. One disadvantage associated with WRELAX is that it converges slowly when the...
متن کاملMultipath time-delay estimation
A transmitted and known signal is observed at the receiver through more than one path in additive noise. The problem is to estimate the number of paths and for each of them the associated attenuation and delay. It is a frequent problem in sonar, radar and geophysics. We propose an algorithm that is easy to implement, that has a reasonable computational load and seems to be able to solve the pro...
متن کاملTitle Super - resolution time delay estimation in multipathenvironments
The problem of super-resolution time delay estimation in multipath environments is addressed in this paper. Two cases, active and passive systems, are considered. The time delay estimation is first converted into a sinusoidal parameter estimation problem. Then the sinusoidal parameters are estimated by generalizing the Multiple Signal Classification (MUSIC) algorithm for single-experiment data....
متن کاملTime-delay Estimation in Time-warping Environments
Time-delay estimation (TDE) is a common requirement of the ranging and localization systems often found in unattended ground sensors. In this paper we consider novel approaches to the TDE problem in a time-warping acoustic environment, such as that encountered when the propagation velocity is not constant—due to wind gusts, for example. An increasing propagation velocity induces a compression o...
متن کاملBayesian Time Delay Estimation of GNSS Signals in Dynamic Multipath Environments
A sequential Bayesian estimation algorithm for multipath mitigation is presented, with an underlying movement model that is especially designed for dynamic channel scenarios. In order to facilitate efficient integration into receiver tracking loops, it builds upon complexity reduction concepts that previously have been applied within maximum likelihood (ML) estimators. To demonstrate its capabi...
