In this paper,an intact time and frequency synchronization scheme was presented based on the preamble and the pilots for the OFDM UWB system specified in the IEEE802.15.3c standard.An anti-multipath separated sliding correlation detection(SSCD)method was proposed based on the Gray complementary sequences,and the positions of the correlation peaks were averaged to increase the anti-noise capability of timing.A sampling frequency synchronization method was also presented for doing phase equalization combined with integer sampling deviation pre-correction(PE-ISDPC),which could exploit the tolerance of the cyclic prefix to the integer sample deviation,reducing the implementation complexity.Simulation results show that the system has a better performance of time and frequency synchronization,and the complexity of overall scheme is low.
