Multi-dimensional K-factor analysis for V2V radio channels in open sub-urban street crossings
In this paper we analyze the Ricean K-factor for vehicle-to-vehicle (V2V) communications in a typical open suburban street crossing. The channel conditions vary from non line-of sight (NLOS) to line-of-sight (LOS). The antenna arrays used for recording the radio channels consist of 4 elements with directional radiation patterns. We measured 16 individual singleinput single-output channels, with a bandwidth of 240 MHz for a duration of 20 s. We performed two kind of evaluations. For the first analysis we partitioned the 240 MHz bandwidth into 24 sub-bands with 10 MHz each, according to 802.11p. The smallscale fading of the first delay bin is Ricean distributed with a time-varying K-factor. The later delay bins are mostly Rayleigh distributed. We observe that the large/small K-factor values are not necessarily correlated with the received power. We show that the K-factor can not be assumed to be constant in time, frequency, and space. The antenna radiation patterns, and the illuminated o...
