摘要
介绍了超宽带技术及其标准化进程,阐述了基于正交频分复用(OFDM)技术的超宽带系统的设计思想和基本原理,分析多频带正交频分复用超宽带(MB-OFDM-UWB)系统中的关键技术和系统性能.研究结果表明,凭借OFDM技术应用于超宽带系统的优势,基于OFDM技术的超宽带方案得到了业内绝大多数厂商的支持,有望成为超宽带物理层的标准.
The ultra wideband communication technology and its standardized advancement are demonstrated. The design idea and basic principle are proposed based on orthogonal frequency division multiplexing technology. The essential technique and system performance of the multi-band orthogonal frequency division multiplexing ultra-wideband system are analysed. The research result indicates that, due to the technical superiority of the application of OFDM to the UWB systems, UWB scheme based on the OFDM technology has obtained supports from most of the manufacturers, and is expected to become the standard of the physical layer of UWB.
