Multi-UAVs Payload Data Communication with Asynchronous Access

This paper study the payload data communication of multi-UAVs system, and propose the system architecture. Considering the asynchronous interference of multi-UAVs communication, the filtered-OFDM is introduced to suppress the out-of-band emission and mitigate the inter-subband interference. According to simulation results, the proposed multi-UAVs system based on F-OFDM that is superior to OFDMA scheme in asynchronous interference suppression and spectral efficiency. Finally, we valid the multi-UAVs communication system work well under the considered air-to-ground channel.
