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, semianalog methods have been motivated recently. We have recently proposed 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 welldesigned polarity codes. The algorithm requires sampling at the frame rate only and bypasses channel estimation during the synchronization phase. This paper analyzes the identifiability and both the probability of acquisition and the the mean square error performance of CABS analytically. A data-aided code-assisted synchronization CAS algorithm is also proposed and a modified version of CABS which relies solely on the time hopping code is investigated.
