Quantitative assessment of site diversity from rainfall spatial correlation characteristics

Satellite communication using high frequency is expected to transmit much information. But this technology has a communication impediment due to rainfall. The higher frequency we use, the bigger impediment occurs. There are some countermeasures to this phenomenon. One of those is site diversity. The quantitative evaluation of site diversity that how much distance apart between two receiving stations, how much effectiveness can be obtained has not been discussed by data measured in a short period of time. So, we researched effect when we carry out site diversity between two sites using by Japanese rainfall data measured every 1 minute.
