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致力于研究和开发用于无线多址通信和传感器网络的光纤超宽带(UWB-Over-Fibre)技术。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，为宽带无线接入和传感器网络寻找创新的UWB光纤技术。UWB于2002年被美国联邦通信委员会批准在3.1-10.6 GHz范围内未经许可使用，吸引了人们对短距离高通量无线通信和传感器网络的极大兴趣。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。为了提供跨不同网络的不中断服务的可用性，并最终实现随时随地的高数据速率接入，解决方案是将UWB与最先进的光纤分配技术相结合，这一新领域被称为UWB over Fibre。在这项拟议的研究计划中，我们将研究和开发基于基于直接序列码分多址编码的光产生的UWB信号的光纤UWB技术，以及用于多用户宽带无线通信和传感器网络的相关光电子元件。

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.
