A simple scheme to generate power-efficient FCC-compliant UWB pulses is proposed by using a dual-drive Mach-Zehnder modulator (DD-MZM). By adjusting the working parameters of the DD-MZM, a UWB quasi-quadruplet pulse with a spectral power efficiency of 49.2% and a 10-dB bandwidth of 6.22 GHz is obtained via computer simulations. Furthermore, this UWB generator can potentially support multiple modulation...
