Abstract

A method is proposed to evaluate the interference of ultrawideband (UWB) signals to other systems outside its frequency band, by introducing two critical parameters W_ob and P_ob. These two parameters represent the total bandwidth and total power of the UWB signal to be evaluated exceeding the frequency mask, respectively. W_ob is the bandwidth out of the frequency mask limit and P_ob is the signal power exceeding the frequency mask. At last, the derivatives of the Gaussian pulse are evaluated up to third order, i.e. monocycle, doublet and triplet, when the original Gaussian pulse width varies from 60 to 350 ps. The results show that the interference introduced to outside band by the UWB signal decreases at first and then increases and finally decreases again, when the original Gaussian pulse width increases. To evaluate an optical UWB signal, this evaluation method should be applied after a simple photoelectric conversion.
