Performance analysis of synchronization algorithm based on the improved S-V channel model for UWB systems

Timing synchronization has been one of the largest challenges for Ultra-wideband (UWB) systems. To achieve the excellent performance, synchronization systems must have the characteristics of high speed, high accuracy and low complexity. In another literature, we have proposed a novel synchronization method, Multi-hypothesis Maximum Energy Path Acquisition (MH-MEPA) algorithm, based on the improved S-V channel model proposed by IEEE 802.15.3a group to rapidly realize timing synchronization with high accuracy. To improve the MH-MEPA algorithm, the paper deduces the expressions of the probability of acquisition, mean acquisition time and the error probability and analyzes the effects of the time delay jitter on the detection probability, mean acquisition time and error probability. Simulation results show that the MH-MEPA algorithm outperforms the existing ones, i.e., achieving the smaller mean acquisition time, higher accuracy and lower error probability than others.
