摘要 A comparison of ultra-wideband (UWB) communication characteristics for six different geometrical shapes is investigated. These six shapes include the straight shape corridor with rectangular cross section, the straight shape corridor with arched cross section, the curved shape corridor with rectangular cross section, the curved shape corridor with arched cross section, the L-shape corridor, and the T-shape corridor. The impulse responses of these corridors 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, number of dominate paths (85% energy), and number of significant paths (within 10 dB peak) for these six corridors could be obtained. Numerical results show that the RMS delay spreads for the arched cross section corridors are smaller than those for the rectangular cross section corridors regardless of the shapes. The RMS delay spreads for the T-shape and the L-shape corridors are greater than the other corridors. Finally, the outage probability for binary antipodal-pulse amplitude modulation (B-PAM) system has been calculated.
