摘要

提出了一种基于能量检测的红外-超宽带系统时间同步方案。所提出的同步方案可以在一个符号间隔内实现符号定时同步。在住宅视距(LOS)和非视距(NLOS)传播环境下，比较了该方案与TDLC算法的均方误差(MSE)性能。该时间同步方案具有较低的计算复杂度和较好的均方误差，适用于红外-超宽带通信。

A Low Complexity IR-UWB Receiver for Wireless Sensor Networks

This study proposes an energy detection based time synchronization scheme for IR-UWB systems. The proposed synchronization scheme may achieve symbol timing synchronization within a symbol interval. The mean square error (MSE) performance of the proposed scheme is compared with that of the TDLC algorithm, in both residential line-of-sight (LOS) and non-line-of-sight (NLOS) propagation environments. The proposed time synchronization scheme is appropriate for IR-UWB communications because of its low computation complexity and excellent MSE.
