摘要
文中首先对超宽带中三种发送参考系统作了简要的介绍,包括:发送参考超宽带(TR-UWB)、基于频率参考的超宽带(FSR-UWB)和基于正交码参考的超宽带(COTR-UWB),其次,给出这三种系统的信号模型和接收机结构。最后,用IEEE802.15.4a office NLOS信道模型,对三种发送参考系统的误比特率性能作了仿真,分析结果为:TR-UWB性能最好,而COTR-UWB更具吸引力。
In this paper, three kinds of transmitted-reference Ultra-Wideband（UWB） system are presented, including transmitted reference Ultra-Wideband （TR-UWB） Radio, slightly frequency-shifted reference Ultra-Wideband （FSR-UWB） Radio and Code-Orthogonalized Transmitted-Reference Ultra-Wideband（COTR-UWB） Radio.Then introduce the signal models and receivers of three schemes are given .Finally, this paper describes the simulation on BER performance of the schemes by using IEEE802.15.4a office NLOS channel model, and the result shows that TR-UWB system is the best BER performance while COTR-UWB system more attractive.
