Abstract :
In this paper, we propose a preamble structure and present a coarse timing synchronization method based on it. Performance of the proposed synchronization method is compared to Schmidl´s method in terms of detection, missing, false alarm probability and mean acquisition time. For frequency selective multipath fading channels, our proposed synchronization method has a higher detection probability and a lower false alarm probability than Schmidl´s method at high SNRs (greater than 1 dB). The mean acquisition time of the proposed method is also improved at high SNRs
