摘　　要：构造了一种零相关序列集(ZCZ)作为训练序列,该序列具有理想的自相关和互相关特性。为消除码间干扰和多径干扰,对构造的序列集进行插"0"运算,仿真结果表明该方法有助于提高同步性能。A zero correlation zone sequence（ZCZ） is constructed as a training sequence.Its performance of autocorrelation and cross-correlation is very ideal.Then inserting ＂0＂ into the sequence is used to eliminate inter-symbol interference and multi-path interference.The simulation results demonstrate that the method can effectively improve the performance of synchronization.

关 键 词：DS-UWB 同步 自适应 正交 零相关序列
