Direct-sequence ultra-wideband over fiber technologies for wireless multiple access communications and sensor networks

这项为期五年的研究计划涉及无线多址通信和传感器网络的超宽带光纤（UWB-over-fiber）技术的研究和开发。拟议的理论和实验研究将使我们能够领导加拿大和国际努力，寻找创新的UWB光纤技术，用于宽带无线接入和传感器网络。2002年，美国联邦通信委员会批准UWB在3.1 ~ 10.6 GHz范围内使用，UWB在短距离高吞吐量无线通信和传感器网络中引起了极大的兴趣。这种短距离无线网络可以主要在室内环境中以独立模式运行，几乎不存在与固定有线网络或无线广域基础设施的集成。为了在不同的网络之间提供不间断的服务，并最终实现在任何时间和任何地点的高数据速率接入，一种解决方案是将UWB与最先进的光纤分配技术相结合，这是一个称为UWB over Fiber的新领域。在这个拟议的研究计划中，我们将调查和开发UWB-over-fiber技术的基础上，光产生的UWB信号，编码的基础上直接序列码分多址和相关的光电组件的多用户宽带无线通信和传感器网络。

This five-year research program is concerned with the investigation and development of UltraWideband-over-fiber (UWB-over-fiber) technologies for wireless multiple access communications and sensor networks. The proposed theoretical and experimental research will allow us to lead Canadian and international efforts in searching for innovative UWB-over-fiber technologies for broadband wireless access and sensor networks. UWB, approved by the US Federal Communications Commission in 2002 for unlicensed use from 3.1 to 10.6 GHz, has attracted great interest for short-range high-throughput wireless communications and sensor networks. Such short-range wireless networks can operate mainly in an indoor environment in a stand-alone mode, with nearly nonexistent integration into the fixed wired networks or wireless wide-area infrastructure. To offer availability of undisrupted service across different networks and eventually achieve high-data rate access at any time and from any place, a solution is to combine the UWB with state-of-the-art fiber distribution technology, a new area called UWB over Fiber. In this proposed research program, we will investigate and develop UWB-over-fiber technologies based on optically generated UWB signals that are encoded based on direct sequence code division multiple access and the associated optoelectronic components for multiple user broadband wireless communications and sensor networks.
