Abstract

Comprehensive and well-founded knowledge of the wireless indoor channel is fundamental in order to enable realistic modeling of the dynamic channel characteristics. Many modeling approaches are available in the literature. However, the usage of a single representative channel model is desirable to ensure scientific reproducibility and a common basis for system design. In this paper, the often cited channel model of the IEEE 802.11n task group (TGn) is analyzed in comparison to a large number of channel measurements in home environments. A non-negligible deviation between both approaches can be noticed. In order to overcome this divergence, parameter modifications for the IEEE 802.11n model are proposed to match the measurement results.

设计了基于ofdm的室内无线传输信道模型
为了能够对动态信道特性进行真实的建模,全面而有根据的室内无线信道知识是至关重要的。文献中有许多可用的建模方法。然而,使用单一代表性通道模型是可取的,以确保科学的可重复性和系统设计的共同基础。本文对IEEE 802.11n任务组(TGn)中经常被引用的信道模型进行了分析,并与家庭环境中的大量信道测量进行了比较。可以注意到两种方法之间存在不可忽略的偏差。为了克服这种差异,提出了对IEEE 802.11n模型进行参数修改以匹配测量结果的方法。
