| Summary: | 碩士 === 國立交通大學 === 電子工程系所 === 94 === WiMax is realized by the specification of IEEE 802.16e.It can transmit data over 30 miles and contain the range within 1 mile radius .The transmission system is
implemented by OFDM technique. IEEE 802.16e is the extension of 802.16-2004 structure,which supports both fixed position and mobile transmission environments.
OFDM system is very sensitive to the timing and frequency errors,the effect of timing and frequency error will degrade the system performance seriously.In this paper,a low-complexity algorithm for the frame synchronization of IEEE 802.16e WiMax is proposed.The proposed method is compared with the method proposed by Schmidl and Cox’s in AWGN,mobile,and static mutipath channel，respectively.Simulation results also show that the proposed method can be implemented efficiently with lower complexity.
