摘要：
This paper mainly simulates two Ultra-wideband (UWB) signals and their power spectrum which are time hopping pulse position modulation (TH-PPM) and multi-band orthogonal frequency division multiplexing (MB-OFDM), and also simulates two UWB channels which are IEEE802.15.3 channel and IEEE802.15.4. And through theoretical analysis and computer simulation, we analyzed the performance of the UWB signals TH-PPM and MB-OFDM through the UWB channel environment. In the MATLAB simulation environment, indoor environment of the two cases line of sight (LOS) and not line of sight (NLOS) show that TH-PPM-UWB using RAKE receivers collect multipath energy and having some gains, and MB-OFDM-UWB is simply mixed the multipath energy. The simulation results show that the bit error rate of TH-PPM-UWB is better than MB-OFDM-UWB. In conclusion, TH-PPM-UWB scheme performs much better than MB-OFDM-UWB scheme.
