中文摘要：
提出一种在室内密集多径信道环境下的直扩超宽带（DS-UWB）多用户接收信号的同步捕获方法，并对该方法的性能进行了理论分析和仿真验证．该方法利用冲激脉冲经过密集多径信道后其能量在时间上扩展的特点，采用随机训练序列，结合自适应均衡，以训练序列与判决输出之间的误差均值最小作为判决准则，通过可变步长有重点搜索能量最大区间来实现快速同步．
英文摘要：
A synchronous acquisition scheme is presented for DS-UWB receiver in the presence of multiuser and indoor multipath chaanel environment. It utilizes the delay spread characteristics of the dense multipath channel when the impulse radio signals pass through the channel, introduces the adaptation equalization algorithm with random training sequence,and searches the major energy region using variable synchronous step length and MMSE criteria. The characteristics of the algorithm are analyzed on theories and simulations, which show the scheme realizes the quick synchronization in indoor environment.
