中文摘要：

超宽带无线通信技术具有抗多径干扰、大带宽及低辐射功率等优点，是实现短距宽带无线接入的重要技术。为进一步提高UWB无线通信的覆盖范围，无线接入和光纤传输融合成为趋势。本项目在光载超宽带无线通信脉冲信号的产生、调制与传输上进行了系统性研究，获得多项研究成果。在光生超宽带信号方面，提出了基于光电、全光偏振调制原理的monocycle和doublet脉冲产生方式，并分析了其时频特性；利用微波光子滤波效应产生了多频带的超宽带信号；提出了一种新型构建微波光子滤波器的方法并进行了实验验证。在超宽带信号编码与调制方面，提出了对称相位-强度调制转换结构的脉冲极性及形状调制方式；提出由多个monocycle及doublet脉冲组合非相干叠加实现高辐射效率脉冲光域产生和调制。在超宽带信号的传输方面，搭建了有线与无线结合的光载超宽带信号传输实验平台，在此基础上进行了速率高于3Gb/s的光载超宽带系统实验，进行了超过20km单模光纤的传输并获得了良好的系统性能。发表了超过40篇高水平学术论文，其中SCI论文15篇，申请发明专利2项，超额完成预期指标。本项目研究成果为光载超宽带及微波光子学的研究奠定了坚实的基础。
