Abstract :
This paper presents results of frequency domain measurements conducted using a channel sounder with a 2 GHz sweep bandwidth and omni-directional receive antenna to characterise the RMS delay spread and coherence bandwidth for indoor environments in the band 63.4 GHz-65.4 GHz. The RMS delay spread (τrms) and coherence bandwidth (βc) of the channel are also presented as functions of distance between terminals. The levels below which βc stays for 90% of receiver positions are given for correlation factors of 0.9, 0.7 and 0.5.
