Abstract

In impulse radio ultra-wideband (UWB) systems, when all the users use same pulse waveform, the effects of multi-user interference (MUI) are great, and then the system bit error rate (BER) is deteriorated. In order to reduce the effects of MUI, this paper presents a novel waveform design method based on wavelet-combined waveforms, and this waveform is used in a multiple access system with time hopping (TH) sequence. Meyer wavelet-based combined waveform is employed as an example, and in a TH-BPSK system this design method is analyzed from two aspects: theory and simulation. Results show that combined-waveform can reduce MUI efficiently and reach the goal of adaptive spectrum envelope.
