| 摘 要： | 在满足联邦通信委员会（FCC）频谱限制的基础上，为了避免超宽带系统对现有窄带无线系统的干扰，利用APSWF函数的特性，提出了一种基于多频带的近似回转椭球波函数（APSWFs）基的利用最小均方误差（LSE）准则线性组合来设计超宽带脉冲波形的算法．仿真表明，设计的脉冲功率谱不仅符合FCC频率掩模的约束要求，而且有较高的频谱利用率．

| Abstract: | This paper presents a UWB pulse shaping algorithm, which uses the liner combination of least square error （LSE） based on multiband approximate prolate spheroidal wave functions （APSWFs）. It meets the spectrum restriction of the Federal Communications Commission （FCC） and avoids ultra-wide band system＇ s interference to the existing narrow-band wireless systems. Simulation results show that the pulse waveforms shaped by this method not only conform to the spectral mask of FCC, but also have higher spectrum efficiency. |
