Study on hybrid multibeam satellite communication system with cross frequency bands

The authors propose a combination of high-frequency multibeam and low-frequency single-beam systems to cope with the problem of high rainfall outage. The proposed system is called a crossband hybrid multibeam (CHM) system. The performance of this system is evaluated with respect to rainfall outage and traffic, and a network control scheme is discussed. It is concluded that the use of this system can reduce trunk transmission network costs and enhance reliability
