Performance Analysis of Time of Arrival Estimation on OFDM Signals [PDF]

open access: yesIEEE Signal Processing Letters, 2015
This letter characterizes the error performance of realistically modelled orthogonal frequency division multiplexing (OFDM) signals, when their time of arrival has to be estimated in an additive white Gaussian noise channel. In particular, different power distributions on the available sub-carriers of the OFDM signal are considered, and bounds on the ...

Cramer-Rao bounds in the estimation of time of arrival in fading channels

open access: yesEURASIP Journal on Advances in Signal Processing, 2018
This paper computes the Cramer-Rao bounds for the time of arrival estimation in a multipath Rice and Rayleigh fading scenario, conditioned to the previous estimation of a set of propagation channels, since these channel estimates (correlation between ...
