摘要：
In this paper, robust timing & frequency synchronization techniques for OFDMA (OFDM-FDMA) systems is presented. Under the multi-path channel environment of ITU-R M.1225, Detection Probability, False Alarm, Missing Probabifity, and Mean Acquisition Time of the proposed timing synchronization scheme are compared with the existing method of 141 to demonstrate the excellence of the proposed scheme. MSE (Mean Square Error) and signal constellation to show the performance of carrier frequency offset estimation is also addressed in this paper.
