Abstract
In this paper a measure of performance of time delay estimators arising from a frequency model of the received signal is presented. The aim is to derive theoretical analysis of the Cramer-Rao bound (CRB) for time delay estimation under realistic wireless channel propagation conditions. The derivation of the CRB is considered from the frequency domain signal model yielding a closed-form expression without imposing any constraints on the different propagation paths.
