Synchronization and Integration Region Optimization for UWB TR Signals

In the UWB transmitted reference (TR) schemes, the integration region of a receiver integrator significantly affects the bit error rate (BER) performance. In this paper, a method of synchronizing and estimating the optimal integration region, i.e., the initial point and the length of the integration, is presented. Following a theoretical analysis, a data-aided estimation method using the idea of intersymbol correlation is proposed. It is shown that using the noise corrupted received signals, the proposed method is not only practically applicable, but also enhances the performance compared to non-optimal timing methods.
