Channel models for the design of OFDM-based wireless indoor transmission

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.
