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.
