100Mbps UWB通信系统基带单元的设计与实现

Design and Implementation of the Baseband of 100Mbps UWB Communication Systems

超宽带通信技术与其它通信技术有很大不同,它具有信号功率谱密度低、保密性强、穿透能力强、抗多径干扰等优点,尤其适合于室内等密集多径场所的高速无线接入和军事通信。本文介绍了一种基于TH-PPM的100Mbps超宽带试验通信系统的实现方案,对系统基带信号处理的同步捕获、卷积、交织模块进行了详细的介绍,并在搭建的室内UWB实验平台上得到了验证。

The UWB communication technology has many features that differentiate it from the conventional communication technologies, including low power spectral density, strong security, strong penetrating power, multipath anti-jamming, and so on, which is especially suitable for the high-speed wireless access in dense multi-path environments and military communications. The paper gives a design approach to 100Mbps UWB testing communication systems based on the TH-PPM modulation,and introduces the organization of the system, the principle of working and the scheme of implementation. Meanwhile, the paper detailedly discusses the pivotal portion of the system, which includes the synchronization and acquisition, convolution,and interleaving. Finally, the paper validates the feasibility of the design via an experimental test on the UWB platform in an indoor way.
