摘要：
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. © 2017, Editorial Department of Transaction of Beijing Institute of Technology.
