摘要

本文计算了在室内信道模型下，阴影对超宽带系统的影响。影响802.15.3a室内信道模型性能的各种信道损伤有:内脉冲干扰(IPI)、调制方案类型、窄带干扰(NBI)和Rake接收机组合方案(如EGC、MRC、MMSE)。本文将阴影作为信道损伤考虑在内，并对所考虑的信道模型的性能进行了分析。从分析结果可以清楚地看出，阴影对室内超宽带信道模型的误码率性能有相当大的影响。本文提出了计算阴影影响下平均误码率(ABER)的最简单方法，并通过仿真结果验证了所提出的分析方法。

Effect of shadowing on 802.15.3a UWB channel model

In this paper, the effect of shadowing on the ultra wide band (UWB) system, over the indoor channel model is calculated. Various channel impairments that affect the performance of 802.15.3a indoor channel model are intra pulse interference (IPI), types of modulation scheme, narrow band interference (NBI) and Rake receiver combining scheme e.g. EGC, MRC, MMSE. The shadowing as channel impairment considered in this paper and the performance of considered channel model is find out. From the analytical results it is clear that, shadowing has shown a considerable effect on the BER performance of indoor UWB channel model. This paper is proposing the simplest method to calculate the average bit-error-rate (ABER) for the effect of shadowing and verified this proposed analytical method by the simulated results.
