采用实数编码的遗传算法对超宽带（UWB）波形进行了独特设计。以正弦高斯脉冲作为基函数，提出了一种新的适应度函数表示方法，应用此方法设计出了更符合美国联邦通信委员会（FCC）提出的辐射掩蔽特性要求的脉冲波形，并对设计脉冲进行了链路预算。仿真结果表明：采用实数编码的遗传算法优化设计得到的超宽带波形效果好且仿真时间复杂度低；与随机组合脉冲相比，设计出的脉冲在信号传输性能方面更具优势。

A unique ultra-wideband (UWB)pulse waveform design which using Real-Coded Genetic Algorithm is proposed in this paper. With sine Gaussian pulse as the base function,this paper proposed a new fitness function. This method is designed for more accordance waveform to meet the requirements and the link budget is discussed for the designed pulse. The simulation results show that the Real-Coded Genetic Algorithm waveform design can meet the FCC spectral specification and has lower time complexity in simulation; compared with the random combination pulse,this designed pulse has better spectral utilization efficiency and better transmission performance.
