| 摘 要： | 超宽带（UWB）通信系统利用优化成形脉冲方法，可以产生符合美国联邦通信委员会（FCC）制订的辐射限值的发射信号。此方法在数学表达上简单、清晰。仿真结果表明，该方法可以使UWB成形脉冲的功率谱在高、低频带都能逼近FCC的标准辐射值，得到的组合系数表达简单。在硬件实现时能够减少寄存器数量和提高运算速度。

| Abstract: | An optimized UWB pulse shaping method is proposed to meet the FCC emission mask based on linear combination and Least Square Error(LSE).This mathematical expression is simple and explicit.Simulation results show that high and low PSD parts of UWB pulse can both meet the FCC emission mask,and the real coefficient is used easier for hardware by reducing registers and increasing operating rates. |
