Abstract A new training symbol was designed and a novel time and frequency synchronization scheme for orthogonal frequency division multiplexing systems was proposed. The time synchronization was accomplished by using the symmetric conjugate of the training symbol in time domain and the frequency synchronization was finished by utilizing the good autocorrelation of the training symbol in frequency domain. The simulation results show that the scheme gives very accurate estimates of symbol timing and carrier frequency offset and provides a very wide acquisition range for the carrier frequency offset.
