"Analysis of Code-Assisted Blind Synchronization for UWB Systems"

Timing synchronization is a preeminent challenge in ultra-wideband impulse radios (UWB-IRS). The conventional all-digital synchronization methods encounter some formidable implementation difficulties such as high rate sampling and high complexity RAKE structure. To avoid these challenges, semi-analog methods have been motivated recently. We propose a code-assisted blind synchronization (CABS) algorithm to realize timing synchronization blindly with the help of the discriminative property of both time hopping codes and well designed polarity codes. The algorithm requires sampling at the frame rate only and bypasses channel estimation during the synchronization phase. This paper analyzes the mean square error performance of CABS analytically. Finally, the performance of this algorithm was analyzed u- ing computer simulations.
