Abstract
Aiming at the problem of communication blackout in the near-space aviation, a new anti-blackout communication method is proposed based on carrier aggregation of OFDMA and frequency diversity. The plasma sheath covered by the aerocraft is treated as a wireless fading channel. The same message is modulated onto every subcarrier of OFDMA in different frequency band. Then frequency diversity reception is used to improve the robustness of the data link. The analysis and simulation results show that the method could significantly improve the bit error performance of the communication link through the plasma sheath. This research provides an effective and simple way for anti-blackout communications.
