    摘要: A comparison of UWB communication characteristics for different distribution of people and various materials of walls in real environments is investigated. The impulse responses of these cases are computed by applying shooting and bouncing ray/image (SBR/Image) techniques and inverse Fourier transform. The frequency dependence utilized in the structure on the indoor channel is accounted for in the channel calculation. By using the impulse response of these multi-path channels, the mean excess delay, root mean square (RMS) delay spread, the number of multi-path arrivals within 10 dB of the peak multi-path arrival (NP10dB), and the number of paths required to meet the 85% energy capture threshold (NP (85%)) for these different distribution of people and various materials of walls have been obtained. The bit error rate (BER) performance for UWB indoor communication is calculated. The outage probability for binary antipodal-pulse amplitude modulation (B-PAM) system has been presented. Numerical results have shown that the multi-path effect by people is an important factor for BER performance. Some different distribution of people and various materials of walls have been very carefully investigated. Finally, it is worth noting that in these cases the present work provides not only comparative information but also quantitative information on the performance reduction.
