| Abstract: | In view of the Ultra wide band （UWB） system which transmits data information using ultra-short pulses, this paper presents a kind of ultra-short pulse function which is suitable for the system, namely Modified Hermite Polynomial （MHP）. In the paper, the performance of the pulse waveform is analyzed in time domain and frequency domain. The effects of the time-shaping factor and the orders to the pulse shape and the energy spectrum density are also analyzed. |
