The 60 GHz mobile-to-mobile radio channel-fading statistics and estimated packet error rates

This paper presents the results of 60 GHz mobile-to-mobile radio channel measurements which were carried out on highways, rural roads and in urban surroundings for distances up to 500 m. Fading statistics concerning the duration of fades and the distribution function of the received power are presented. Furthermore, the measured channel data were used for the simulation of a packet transmission in order to predict the packet error rates and the performance of some error control methods, i.e. time diversity, antenna diversity, forward error correction (FEC) and a code combining method. Selected results of highway measurements for distances between the transmitter and receiver from 200 m up to 500 m are presented. The probability density function of the received signal amplitude shows good agreement with a Rice/Rayleigh-lognormal density. For a transmitter power of 14 dBm, a packet length of 259 bit and BPSK-modulation with 500 kbps the estimated mean packet error rate was less than 10^-2 for distances up to 300 m without additional error control. With antenna diversity as well as with the code combining method the estimated mean packet error rate was less than 10^-2 even for vehicles distances up to 500 m
