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.

Driscoll-T.A
The purpose of this document is to give a medium-length introduction to the essentials of
MATLAB and how to use it well. I’m aiming for a document that’s somewhere between a two-
page introduction for a numerical methods course and the excellent but longer Getting Started and
other user guides found in the online docs. I use it in a week-long “boot camp” for graduate
students at the University of Delaware in the summer after their fi rst year of study.
