摘要 在室内短距离无线通信技术中,超宽带(Ultra WideBand,UWB)技术凭借低成本、低功耗、保密性强、抗干扰能力强、传输速率高等优点,近年来得到了广泛的研究与发展,成为宽带无线通信系统的核心技术之一,已经受到学术界和工业界的广泛重视,具有广阔的应用与市场前景。本文以双载波-正交频分复用(dual-carrier orthogonal frequency division multiplexing,DC-OFDM)超宽带系统方案为研究对象,介绍了系统工作原理、发射端和接收端关键模块、频带划分方案等;阐述了超宽带短距离无线通信系统研究中使用的超宽带信道模型,用仿真数据说明了该信道模型的冲击响应特性;并分析了基于该模型的DC-OFDM超宽带系统的误码性能。 In the indoor short-range wireless communication technology,recently UWB technology has been extensively researched and developed with low cost,low power consumption,high confidentiality,good ability to anti-interference and high data transmit speed.UWB has drawn attention from academic line and industrial line as one of core technology of wide-band wireless communication system and it has broad application and market prospect.In the paper,a dual-carrier-orthogonal frequency division multiplexing(DC-OFDM) UWB system scheme is introduced,including its working principle,transmitting end scheme,as well as the key design of receiving end,band-division scheme.UWB channel model in short-distance UWB system is introduced,subsequently the impulse response characteristic of the channel model is illustrated with the simulation data;then the PER result about DC-OFDM UWB system is analyzed.
