A Non-Data-Aided Maximum Likelihood Time Delay Estimator Using Importance Sampling

In this paper, we present a new time delay maximum likelihood estimator based on importance sampling (IS). We show that a grid search and lack of convergence from which most iterative estimators suffer can be avoided. It is assumed that the transmitted data are completely unknown at the receiver. Mo...
