DesignM ethod for Ultra-W ideband Pulse Based on the Parks-M cC lellan Algorithm

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 positionmodulation)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 ofUWB (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)spectralmasks. The relevantdesigning results can be applied in both single-andmulti-band UWB systems.
