摘    要:针对现有椭圆球面波函数(PSWF)脉冲求解算法仿真效率低、直观性差等问题,从PSWF的微分方程定义出发,在Simulink环境中构建PSWF脉冲发生器,给出带通PSWF和具有陷波特性PSWF的脉冲设计方法,根据美国联邦通信委员会(FCC)频谱掩膜和抑制窄带干扰的要求分别产生PSWF脉冲,结果表明,该方法产生的脉冲能较好地满足FCC频谱掩膜要求,实现任意频点不同深度的陷波。

关 键 词:超宽带  脉冲设计  椭圆球面波函数  PSWF脉冲发生器  Simulink仿真

Abstract:Aiming at the problem that the current computation method of Prolate Spheroidal Wave Function(PSWF) is inefficient and intuitive in simulation,this paper constructs a PSWF generator in Simulink according to the differential equation definition of PSWF.The design method for bandpass PSWF with notch depth is given.To take Federal Communications Commission(FCC) spectral mask and narrowband interference into account,different pulses are generated by the Simulink method.The results show that the designed PSWF can meet FCC requirements and achieve variable notch depth at an arbitrary frequency.
Keywords:Ultra-wideband(UWB)  pulse design  Prolate Spheroidal Wave Function(PSWF)  PSWF pulse generator  Simulink simulation
