Synchronization solution for the TDSC-UWB detection method

Abstract

This paper proposes a simple synchronization scheme for a new TR-UWB detection method called Time Delayed Sampling & Correlation (TDSC). The TDSC concept is based on inter-correlation between two waveforms captured by two time delayed samplers. The objective is to determine a synchronization scheme with lowest complexity for silicon integration without affecting the BER performance. A multiple correlator acquisition structure in conjunction with a training sequence and a smoothing procedure is used to estimate the signal correlation. Acquisition speed and BER performance are analyzed using IEEE UWB channel models. Results show that good performance are obtained using few correlators and fast acquisition. © Springer Science+Business Media B.V. 2008.
