Abstract

Different modulation schemes of pseudo-chaotic time hopping for ultra-wideband (UWB) communication systems is proposed in this paper. An integral scheme with PPM, PAM and PAM-PPM modulation is presented. The theoretic analysis expressions of power spectral density of these three UWB signals for the three schemes are given. Compared with the theoretic expressions, the simulation results show that the proposed two approaches have good performance in smoothing the power spectral density within 3 GHz-10 GHz.
