Abstract :
We present joint frame synchronization and frequency offset estimation using a new preamble with pseudo-noise sequences in time domain for orthogonal frequency division multiplexing (OFDM) based wireless communication over Rician fading channel. By the proposed scheme, the accuracy of the timing offset estimator is definitely improved and an estimation range of the frequency offset normalized by the carrier spacing is extremely extended to one half of the total signal bandwidth with only one pilot symbol which has lower PAPR than those in conventional schemes. The performance of the proposed method is shown by simulation
