Channel modelling of short-range radio links at 60 GHz for mobile intervehicle communication

Within the European PROMETHEUS research program, the DLR has the task of investigating the 60 GHz link and developing a channel model. Some propagation effects for the intervehicle radio link, such as power law with distance, oxygen and rain absorption, edge diffraction, and frequency- and time-selectivity, are theoretically examined. The simple two-path propagation model is analyzed for this application and compared with measurement results. The model is then expanded to multipath propagation and compared with a measurement. The minima of the two-path model are filled up by the multipath signal, but the fade durations are still on the order of the suggested packet length
