摘要：
This paper presents a performance comparison of impulse radio ultra wideband (IR-UWB) and multi-band orthogonal frequency division multiplexing (MB-OFDM) for multi-user wireless communication systems. Focusing on the analysis of system performance affected by multi-user interference (MUI) over general additive white Gaussion noise (AWGN) channel, we run a complete system simulation for direct sequence pulse amplitude modulation (DS-PAM), time hopping pulse position modulation(TH-PPM) and MB-OFDM UWB systems. Simulation results show that DS-PAM performs much better than TH-PPM and multi carrier OFDM (MC-OFDM).
