Abstract :
A blind synchronisation method or an OFDM system operating over a wireless frequency selective channel is presented. There are two restrictions (i) the constellation on each subcarrier must have points equally spaced in phase and (ii) the length of the guard interval must be chosen from a subset of allowed values. The frequency offset acquisition range is ~±1/8 of the total OFDM symbol bandwidth
