| 摘 要： | 针对认知超宽带与现存窄带系统干扰问题,采用Polycycle信号作为超宽带原始脉冲,使用Hermite矩阵特征向量方法设计了认知超宽带自适应脉冲,实现了干扰抑制.仿真结果表明,提出的自适应脉冲功率谱密度分布符合FCC室内和室外频谱规范,实现了自适应频段陷波.基于PAM-TH UWB系统性能分析表明自适应脉冲具有较强的多用户干扰和窄带干扰抑制能力.

| Abstract: | The cognitive ultra-wideband(UWB) adaptive pulses design method is presented based on Hermite matrix eigenvectors and polycycle signal to make the UWB system coexist with the existing narrow band systems.Simulation results show that the power spectral density(PSD) of the proposed adaptive UWB pulses meets with Federal Communications Commission(FCC) indoor and outdoor spectral mask and produces adaptive spectral notches.Finally,according to analysis and simulation of multi-user interference(MUI) suppression ... |

| Keywords: | ultra-wideband polycycle pulse Hermite matrix spectral notch interference suppression |
