Abstract

timing and frequency synchronization are the important task in receiver. In this paper, an efficient timing and carrier frequency offset (CFO) estimation method for orthogonal frequency division multiple access! time division duplexing (OFDMAffDD) mode in IEEE 802.16-2004standard (WiMAX) is represented. This method has high performance and jointly estimates timing error and CFO. The performance is evaluated in additive white Gaussian noise (AWGN) channel. This method can be easily used for other OFDM based systems which receiver knows preamble at itself.
