<p>A receiver for detecting and recovering data from Orthogonal Frequency Division Multiplexed (OFDM) symbols, the OFDM symbols including pilot data arranged in accordance with a pilot pattern and a guard interval. The receiver comprises a demodulator (602), a symbol synchronisation unit (603) comprising a plurality of correlators to auto correlate each sampled OFDM symbol between a length of samples corresponding to one of the plurality of predetermined lengths of guard intervals, a frequency transform processor (605) and a coarse frequency offset detector (606) including a pilot data filter.</p> |
