Abstract
A main obstacle to limit the capacity of next generation Terabit/s broadband satellite communication is the limited spectrum available in the Ka band. A feasible solution is to move the feeder link to the higher Q/V band, where spectrum is more available. However, the Q/V band is sensitive to rainfall attenuation. Compensating for the falling caused by rainfall, gateway diversity is considered to ensure the required feeder link availability. So far, many strategies for gateway diversity have been proposed, and each of them has its own advantages, so it is imperative to research gateway switching strategies. In this paper, a modified switch and stay combining strategy named TH-SSC is proposed for a Q/V band feeder link, which is suitable for three gateways to switch and we make an analysis and simulations about its performance. It can be seen that this modified TH-SSC strategy is pragmatic and has better performance in some aspects.
