| 摘 要： | 首先分析了在超宽带系统中高斯脉冲成形因子和微分阶数对其能量谱密度的影响,并在此基础上,为了提高高斯脉冲波形的频谱利用率,采用高斯导函数线性组合来产生脉冲波形,提出并分析了一种基于粒子群（PSO）优化算法的超宽带无线脉冲波形优化设计方法,仿真表明该方法产生的高斯导函数线性组合脉冲能够很好地满足FCC的频谱掩模限制。

| Abstract: | Firstly,the power spectral density of the signal influence on Gaussian derivative functions order and shaping factor of Gaussian monocycle in Ultra-Wideband(UWB)is analyzed,and then,for the purpose of improving the spectrum utilization of Gaussian pulse waveform,using the method of combination Gaussian derivatives pulse,a pulse shape design based on particle swarm optimization(PSO) for UWB system is introduced.The simulation results show that the linear Gaussian combined UWB pulses meet the power spectral c... |
