Ergodic Capacity of High Throughput Satellite Systems With Mixed FSO-RF Transmission
Kong Huaicong, Lin Min, Wang Zining +2
We study a high throughput satellite system, where the feeder link uses free-space optical (FSO) and the user link uses radio frequency (RF) communication. In particular, we first…
