摘　　要：讨论了扩展二次跳时序列和一般二次跳时序列及其特殊形式序列的构造,比较了它们的汉明互相关特性.在此基础上,比较了在PPM调制方式下基于这几类二次跳时序列的UWB系统的误码率,并给出了数值结果.研究结果表明,这几类二次跳时序列系统误码率相当一致,但一般二次跳时序列集具有更多的序列数目.Structures of the extended quadratic time-hopping sequences, the general class of quadratic time-hopping sequences and some of their special kinds were discussed. Their Hamming crosscorrelation properties were compared. Based on the discussion and comparison, the error rate of the ultra-wide band （UWB） systems with these quadratic time-hopping sequences and pulse position modulation （PPM） were compared, and the numerical results were presented. It is shown that these quadratic time-hopping sequences have the same system performance, and the general class of quadratic time-hopping sequences have a larger family size.
