Abstract :
The use of "site diversity" to counter the severe rain attenuation in a small area (like Singapore) where optimum baseline orientation with respect to the propagation path is not achievable, has been investigated. Preliminary results of site diversity experiments carried out in Singapore at Ku-band using the INTELSAT beacon are presented. This experiment is accomplished with a site separation of 12.3 km and nonconventional base line orientation of 4/spl deg/. Comparison with the ITU-R models is also presented. This study is the first of its kind in the region.
