%X This paper presents an intact scheme of timing synchronization for the Multi-Band OFDM (MB-OFDM) Ultra Wide Band (UWB) system adopted by IEEE 802.15.3a proposal and ECMA-368 standard. The scheme is determined through algorithm improvement and simulation. Frame detection and coarse timing are implemented with the Maximum Correlation (MC) method based on the first-band information of the preamble. Fine timing is achieved with the minimum energy ratio method based on the information of all the three bands. Besides, revision of the timing position is performed twice that performance of the algorithm is guaranteed. Simulations show that residual timing error can be kept at a small scale which can be compensated with channel in frequency domain. And else, the scheme has a low complexity.
