Abstract

This study proposes an energy detection based time synchronization scheme for IR-UWB systems. The proposed synchronization scheme may achieve symbol timing synchronization within a symbol interval. The mean square error (MSE) performance of the proposed scheme is compared with that of the TDLC algorithm, in both residential line-of-sight (LOS) and non-line-of-sight (NLOS) propagation environments. The proposed time synchronization scheme is appropriate for IR-UWB communications because of its low computation complexity and excellent MSE.
