Research and application of key technologies for high-capacity microwave oversea transmission

In high-capacity microwave oversea transmission, the fading which caused by the multipath propagation interference, effects the microwave signal badly. Based on the analysis of key technology for high-capacity microwave oversea transmission, this paper studies a solution adopting siting design, dual spatial diversity and multiple frequency diversity, as well as antenna Hi-Lo method together. The solution is applied on microwave oversea long-distance transmission between Shantou and Nanao and improves the performance successfully.
