- According to the 60 GHz OFDM-UWB system of IEEE 802.15.3c standard, the characteristics of the preamble Golay complementary sequence are analyzed for better timing synchronization scheme that can resist multipath interference. The normalized autocorrelation method is used to detect the falling edge for frame detection and coarse timing. And then, the autocorrelation of the Gray complementary sequence is used to find the average value of several peaks for fine timing. Simulation results show that the proposed scheme can control the residual timing offset, and the algorithm has low complexity and high timing accuracy. Moreover, the MSRE with fine timing can reach 10-3 orders of magnitude in the CM1 multipath channel with low SNR, which effectively resists multipath interference.
