| 摘 要： | 提出了一种基于高斯二阶导数组合的UWB脉冲波形设计方法.依据FCC对超宽带各频段带宽划分的不同及各频段辐射限制的差异来选取基函数,利用最小均方误差准则(LSE),以FCC室内辐射掩蔽为规范选取一组加权系数对基函数进行线性组合.再通过调整基函数参数脉冲形成因子和搬移因子,对波形进一步优化.仿真结果表明,文中设计脉冲实现了在全频段对辐射掩蔽的高效逼近,与基于随机系数选择的组合脉冲比较:方法简单,具有更高的频谱利用率.

| Abstract: | A pulse waveform design method for ultra wideband(UWB) communication based on combination of the second Gaussian pulse derivatives is presented.The basis functions are chosen according to the different UWB frequency band width and the difference in the different frequency band of restriction of emission mask which regulated by federal communications commission(FCC),the weighting coefficients based on mean square error(LSE) is made certain according to the FCC UWB indoor spectral mask are acted as linear com... |
