Abstract

The high-altitude platform (HAP), located in the stratosphere, connects with satellites upward and low-altitude unmanned aerial vehicle, it can effectively support space-air-ground integrated information networks, and provides flexible emergency communications. However, for the downlink form HAP to unmanned aerial vehicle (UAV), the traditional algorithm tends to be fixed rate, which reduces average transmission rate and improve the outage probability. Rate adaptation-based free space optical and RF dynamic switching (RADS) algorithm is proposed in this paper. In RADS algorithm, FSO link is considered as a primary link, while the RF link is used as backup when the quality of FSO link becomes unacceptable. In addition, according to the signal-to-noise ratio of received signal, the transmission mode meeting the requirements of the minimum bit error rate is adopted to meet the rate requirements. The results show that RADS algorithm outperform than traditional algorithm in terms of outage probability and data rate.

Key words： high-altitude platform; unmanned aerial vehicle; free space optical; signal noise ratio; rate adaptation
