| 摘 要： | 超宽带(UWB)传输技术以其低功耗、高速率和强多径分辨能力等特点而在近年受到广泛重视.超宽带信号在室内环境中将经历密集多径传播,产生严重的时间弥散.提出一种基于MMSE均衡算法rake接收机,它联合rake结构和均衡结构的优点来抑制符号问干扰(ISI),通过matlab比较MRc-rake接收机和MMSE-Eq-rake接收机的误码率,MMSE-Eq-rake接收机的系统性能较优.

| Abstract: | UWB technology has attracted much attention in recent years because of its high data rate,low power consumption,low probability of detection and low probability of interception.In indoor environment,UWB signals suffer from dense multi-path propagation and server time dispersion.The performance of a joint rake and minimum mean square error(MMSE) equalizer receiver for high data rate ultra-wideband communications is studied in this paper.The proposed receiver combats inter-symbol interference by taking advant... |
