| 摘 要： | 首先介绍一种回转椭球波函数(Prolate Spheroidal Wave Functions,PSWF),主要阐述了PSWF的相关概念、特性及其近似求解算法,然后阐述应用PSWF脉冲基来组合设计UWB脉冲波形的算法。如果要求陷波点有干扰抑制,可以对该点左右两侧的频段分别求对应的频域波形,再做相应线性变换,使陷波点的频域值为0,然后对两个脉冲的时域波形做同样的变换,即得所求脉冲波形,最后通过仿真验证了算法的有效性。

| Abstract: | Firstly the Prolate Spheroidal Wave Functions（PSWF） is introduced, including the related concepts, properties and approximation algorithm, then the pulse waveform design in ultra-wideband wireless communication system is analyzed. If interference suppression at the notch point is required, corresponding frequency domain waveform of both right and left side of the notch point needs to be computed, and the corresponding linear transformation is done as following, so that the notch frequency points is zero, then the same transformation is done to the time-domain of the pulses, after that the required pulses waveform is got. At last simulation results show the effectiveness of the algorithm. |
