| 摘 要： | 针对UWB（ultra-wide band）脉冲波形的特点，提出了基于Parks-McClellan算法的UWB无线脉冲波形的优化设计方法，其基本思想是将UWB无线脉冲波形的优化设计等效为FIR（finite impulse response）滤波器的优化设计问题．对单周脉冲采用TH（time hopping）和二进制PPM（pulse position modulation）处理后得到的单频带和多频带模式UWB脉冲波形可充分满足FCC（federal communication committee）的频谱要求，相应的结果适用于单频带和多频带模式UWB系统．

| Abstract: | According to the characteristics of UWB(ultra-wide band) pulse waveforms,a new pulse shape design method for UWB radios based on Parks-McClellan algorithm was proposed.In the method,the pulse shape design is taken as optimal design of a FIR(finite impulse response) filter.TH(time hopping) and PPM(pulse position modulation) technology was adopted for monocycle pulse,which optimally utilizes the bandwidth determined by the FCC(federal communication committee)spectral masks.The relevant designing results can be applied in both single-and multi-band UWB systems. |
