In this paper, a new data-aided joint timing and carrier frequency offset estimation algorithm in OFDM/OQAM system is proposed by utilizing identical central-symmetry ZC sequences before polyphase structure efficient implementation. Based on excellent auto-correlation performance of ZC sequence we derive a timing offset estimator with high accuracy and arbitrary capture range compared with two existed approaches. After the precision timing, a new frequency offset estimator is proposed by two parts, which considered both the identical and central-symmetry properties separately. Computer simulation indicates conspicuous performance improvement in timing offset and frequency offset estimation, especially in a AWGN channel which the proposed method possesses significant advantages while in multipath channel the new estimator can still reveal better performance when selecting the correct weighting factor.
