Robust timing & frequency synchronization techniques for OFDM-FDMA systems

초록

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 Probability, and Mean Acquisition Time of the proposed timing synchronization scheme are compared with the existing method of [4] 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.
