| 摘 要： | 由于UWB主要应用在密集多径的室内环境，所以研究多径效应造成的码间干扰对于设计高速UWB系统非常重要。分析了基于跳时多址的UWB的码间干扰效应。通过分析脉冲的各个多径分量与之后发送的脉冲的时间差的分布，得到了跳时UWB的码间干扰估算公式。与采用等间距发送脉冲时的码问干扰对比，结果显示，随着脉冲重复周期增大，跳时UWB的码间干扰的改善的速度比等间距发送脉冲时缓慢。

| Abstract: | UWB is mostly applied in dense multipath indoor circumstance.The Inter Chip Interference(ICI) caused by multipath is very important for designing a high rate UWB system.The ICI of TH-UWB is studied in this paper.Based on analysis of the probability distribution of the time between the reflections of former pulse and the latter one,an estimated formula of ICI is derived.The analysis shows that the improvement of ICI from increasing the pulse repetition period is slower than equidistance transmitting pulse when the manner of transmitting pulse is time hopping. |
