Abstract:

A new frame synchronization scheme in orthogonal frequency-division multiplexing (OFDM) system was proposed. Based on a central-symmetric training sequence, the miss detection probability of a training sequence in the proposed algorithm could be as small as 10-3 when signal noise rate is 10 dB and the false alarm probability is assumed to be 10-3. Carrier frequency offset could also be partially corrected within sub-carrier spacing of 0.5 as soon as frame synchronization is performed.
