| 摘 要： | 超宽带信道模型中多径分量的到达采用了两个泊松随机过程,各径幅度衰落服从对数正态分布,对模型的仿真和分析结果表明:超宽带信道中存在较多可分离的多径分量,通过Rake接收技术对这些多径分量有效的合并,能提高超宽带系统的性能,由于多径信号衰落的非递减性,采用选择Rake技术的性能优于部分Rake.

| Abstract: | In Ultra Wideband (UWB) channel, two Poisson processes are adopted to describe the multi-path arrival, and the path amplitudes fit the Lognormal distribution. The analysis and simulation of UWB channel model show that there are many multi-path components of very fine resolution. The effective combination of these multi-path components can improve the performance of UWB systems by employing the Rake receiver, and the selective Rake receiver has greater gain than the partial Rake receiver due to the none-of-degression of multi-path fading. |
