Out of vehicle channel sounding in 5.8 GHz band

Abstract

The article presents out-of-vehicle channel measurement results in the 5.8 GHz frequency band which is used in the IEEE 802.11p standard. Experiments for two different distances and three different angles around the parked car are carried out. It is found that a two-term exponential decay model can satisfactorily describe the mean measured power delay profiles. For each measurement, this large scale variation is used to calculate the corresponding channel impulse response and to construct a Rician tap-delay multipath channel model. Bit error rate (BER) performance for each measured location is then evaluated through MATLAB based simulation. The simulation results indicate that the error performances do not vary much and it is possible to determine an average BER curve for the whole set of data.
