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

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.
