一种提高超宽带无线系统干扰容限的方法
A Method to Raise the Interference Tolerance Margin of UWB System
摘要
Abstract
UWB(Ultra Wideband) radio system is easily affected by strong narrow band interference.Traditional interference suppression methods using adaptive notch filter as a preprocessing unit can hardly be used due to high sampling speed in UWB receivers. In this paper, we proposed a novel parallel notch filter based on TDM (Time-division multiplexing) technique, which can effectively track and eliminate multi-band interference, and extremely raise the interference tolerance margin of the UWB wireless communication system when it is used as a preprocessing unit before dispreading.Moreover,the filter structure has such advantages as good stability,high convergence speed, low signal distortion. The numerical results validated the expected performance and properties.关键词
