Wideband indoor and outdoor multipath channel measurements at 17 GHz

This paper presents the results of wideband channel measurements and characterization at 17 GHz. Important channel parameters, namely root-mean-square delay spread, Ricean K-factor, propagation loss factor and their statistics are investigated. The measurements were performed for different types of scenarios and for both indoor and outdoor environments. All channel parameters were derived from the power transfer function solely. The path loss factor is found to be lower than the free space attenuation for all LOS sites. The mean value of the Ricean K-factor is 1.5 dB and -1.1 dB for LOS and OBS indoor sites, respectively. For the outdoor environment 4.9 dB was found. The RMS delay spread was found to be about 20 ns for indoor sites, whereas for outdoor sites the average value was two times higher
