Abstract [en]

In this paper we present a simultaneous maximum likelihood estimator (ML) for time delay and time-scaling in the presence of additive white Gaussian Noise. The Cram´er- Rao lower bound for the variance of the estimates is also derived. The performance of the estimator is evaluated for ultrasound echoes for different time-scalings and different time delays. The performance is compared to the standard cross-correlation estimator.
