This paper investigates timing recovery for differential transmitted reference ultra-wideband receivers. The detector computes the decision statistic by correlating pulses from adjacent frames and summing the contributions from all the frames of a symbol. Synchronization consists of providing accurate timing for the correlation computations. A solution to this problem is proposed that requires a limited amount of extra circuitry. No training sequences are needed as the synchronizer operates in a blind mode. Two possible receiver architectures are envisioned, analog and digital. The effects of the timing errors on the receiver performance are investigated by simulation.
