MILLIMETER-WAVE INDOOR CHANNEL CHARACTERIZATION FORBROADBAND WIRELESS LOCAL AREA NETWOKS

摘要

In this paper, the 60 GHz propagation channelcharacteristics like power delay profiles, rms delayspread, Ricean K-factor and cross polarizationdiscrimination (XPD) are investigated based on indoorchannel measurements performed in a corridor (LOS) anda hall for both LOS and NLOS measurement scenarios. Itis found that in the corridor the multipath componentsshow more clustering property than in the LOS hall. Therms delay spread ranges from 3 ns to 80 ns in indoorenvironments at 60 GHz. The large values of Ricean K-factor indicate stronger LOS component in the channel.The obtained XPD values for the corridor LOSenvironment are quite high in this frequency band.Moreover, the multipath channel dependencies ofdifferent characteristics are also examined. It is noticedthat the K-factor increases with the decrease of channelrms delay spread in general, and low correlation propertybetween the XPD and delay spread can be established.The presented results can be used for the design of 60GHz radio systems.
