On the basis of the study of S&C and Park algorithms
this paper proposes an improved training-sequence-based OFDM synchronization algorithm
in which only one training sequence is used.By using this algorithm
the plateau in timing synchronization is eliminated by multiplying the training sequence by difference sequence in time domain and the integer-carrier frequency offset estimated by the self-correlation of the training sequence between the receiver and transmitter in frequency domain.It is much better than the S&C algorithm in timing synchronization and carrier frequency offset correction.
