Description: An effecient algorithm has been proposed by
Schmidl and Cox for carrier frequency estimation in orthogonal
frequency-division multiplexing systems. The scheme is based
on the transmission of a training symbol composed of two
identical halves in the time domain. In this paper we extend
this algorithm by considering a training symbol composed of
L>2 identical parts. This makes it possible to achieve a better
accuracy at the cost of some increase in computational load. The
estimation range can be made as large as desired without the
need of a second training symbol, as required by the Schmidl
and Cox method.
