Abstract(in English) In this report, as a method being suitable for long-range oversea propagation, we propose a configuration method of space-diversity which uses antennas placed in the relation to obtain negative correlation characteristic. According to our proposal, we have performed a field test by use of a 5GHz FWA system. In this field test, we located a radio station in Rusutsu-Mura in Hokkaido and the one in Yakumo-Cho, Hokkaido, and the distance, which includes the oversea propagation section, between two stations was 75km.Based on the result of the long-term field test, we clarify that the method we propose is effective to fading caused by reflected waves from an ocean surface. In addition, we describe effects of attenuation fading which makes negative correlation characteristics worse and is peculiar to long-range propagation.
