Abstract :
This paper puts the emphasis on symbol timing issues in DC-OFDM based UWB systems. We divide the synchronization process into four modules by functionality: packet detection, coarse timing, TFC detection and fine timing. In the aspect of algorithm development, we adopt the joint auto-correlation and cross-correlation method to meet the requirements of UWB system in different indoor multi-path environments, and therefore achieve the robustness.
