For OFDM transmissions, synchronization is one of the
most performance critical operations. Synchronization is
needed for preservation of orthogonality: timing offsets
and frequency offsets destroy easily this orthogonality,
leading to Inter-Symbol Interference (ISI) as well as Inter
Carrier Interference (ICI).
This paper is focused on the implementation of a
synchronizer for the IEEE 802.11a standard , which is
based on the OFDM transmission scheme. Details on the
different blocks included in this implementation are
provided. We finish our exposition with a comparison of
our solution, which is based on the one presented in 
with two other solutions found in the literature in  and
