Abstract

This paper deals with the short and long distance (10-1400 km) site-diversity (SD) characteristics by using a newly developed measuring system. In the proposed measuring method six Earth-stations transmit QPSK signals and one measuring Earth-station receives signals and processes them for site-diversity characteristics. As a result, easy operation and maintenance, low cost measuring system construction and high accuracy data can be obtained. By comparing these measured results with the site-diversity joint probability approximation equation in CCIR Rep. 564-4, relatively good agreement can be found.
