In this paper, we present a novel data-based method for simultaneous Maximum Likelihood
(ML) symbol and carrier-frequency o畇et estimation in Orthogonal frequencydivision
multiplexing (OFDM) systems. Statistical properties introduced by the cyclic
pre痻, a guard space between OFDM symbols, provide su眂ient information about the
unknown parameters. It is shown that the redundancy introduced by this cyclic pre痻
allows the estimation to be performed without additional pilots. Simulations show that
the performance of the frequency estimator is applicable in a tracking mode while the
timing estimation can be used in an acquisition mode.

OscarV3.14
OSCAR is an optical FFT code used to calculate the steady state optical
eld circulating in Fabry Perot cavities. The code can integrate non-sperical
mirrors and any arbitrary input elds. Recent applications for OSCAR have
been: calculation of thermal lensing eect and calculation of diraction loss
and cavity eigen modes for mesa beams. One great advantage of OSCAR is
the simplicity and
exibility of the code, everyone with only minimal knowl-
edge of Matlab can easily modied OSCAR code to suit specc purposes.
