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