【摘要】 超宽带(UWB)无线电系统与现有通信系统共用频段,窄带系统会干扰甚至阻塞UWB接收机。本文介绍了最小均方误差(MMSE)的RAKE接收机,分析了它的结构及性能,并用计算机仿真进行了验证。结果表明,这种方法可以有效地消除窄带干扰。更多还原

【Abstract】 Ultra-wide band(UWB) radio systems share the same frequency band with the existent systems.The narrow band systems may interfere even jam the UWB receiver.This paper introduces narrow band interference(NBI) suppression algorithms used MMSE-RAKE receiver, moreover,the structure and performance are analyzed.Through some computer simulations the conclusions are verified.The results indicate that the NBI can be eliminated efficiently.更多还原
