| 摘 要： | 在脉冲UWB系统中，应用零相关扩频码（ZCD）进行DA（数据辅助）信道估计，仿真结果显示出采用ZCD码进行信道估计得到的自相关函数优于采用Walsh码得到的．同时提出一种基于ZCD码的脉冲UWB系统的非结构化DA信道估计方法，仿真结果表明，这种方法的误码率低于普通扩频码的误码率，说明该方法可以有效地提高非结构化信道估计的性能．

| Abstract: | In the pulse UWB system, this paper applied zero correlation duration code （ZCD） to DA （data-aided） channel estimation, and the results by the simulation indicated that ZCD code performed better than Walsh code in channel estimation. Meanwhile this paper proposed a method of unstructured DA channel estimation based on the pulse UWB system with ZCD code,and the simalation results showed that the BER （ Bit Error Rate） of this method is lower than the one of ordinary duration code and explained that this method may effectively improve the performance of the unstructured channel estimation. |
