Cramer-rao bound for time-delay estimation in the frequency domain
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.Peer ReviewedPostprint (published version
