ML estimation of time and frequency offset in OFDM systems

van De Beek, Jan-Jaap ; Sandell, Magnus and Börjesson, Per Ola LU (1997) In IEEE Transactions on Signal Processing 45(7). p.1800-1805
Abstract
We present the joint maximum likelihood (ML) symbol-time and carrier-frequency offset estimator in orthogonal frequency-division multiplexing (OFDM) systems. Redundant information contained within the cyclic prefix enables this estimation without additional pilots. Simulations show that the frequency estimator may be used in a tracking mode and the time estimator in an acquisition mode.
