Abstract :
A new training symbol is designed and a novel timing and frequency synchronization scheme for orthogonal frequency division multiplexing systems is proposed. The timing synchronization is accomplished by using the symmetric conjugate of the training symbol in time domain and the frequency synchronization is 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.
