Abstract:

A design method for the Ultra Wideband (UWB) pulse with the optimal combination of differential Gaussian pulses is investigated. A series of the optimal simple order differential Gaussian pulses are constructed using energy shift action of the differential factor and the spectral spreading effect of the pulse shaping factor. According to indoor and outdoor radiation mask standard, an optimal solution of the weight factor is derived by the restrained minimum mean square error algorithm; and a universal UWB combined pulse compatible with the indoor and outdoor transmission environments at whole frequency band is designed. The simulation results indicate that the designed combined pulse is characterized by good capability of approach to the Federal Communication Commission radiation mask standard and least bit error rate under multiuser interference environment. The proposed design method is important to the rational design of UWB pulse with a given frequency spectrum.

Key words: communication, ultra wideband(UWB), radiation mask, differential Gaussian pulse, weight factor, bit error rate
