Timing and frequency synchronization are the important task in receiver. This paper proposes a timing synchronization and carrier frequency offset (CFO) estimation algorithm for orthogonal frequency division multiple access (OFDMA) downlink in IEEE 802.16e standard. This method has high performance and estimates CFO. The proposed scheme utilizes the conjugate symmetry property of preamble structure. Simulations are conducted for AWGN and multipath channels to demonstrate the performance of the proposed timing metric. Our proposed method can achieve reasonable performance at low SNR.
