Wireless communication for a video transmission system with a high data rate is needed to acquire real-time video streaming effectively and efficiently from an Unmanned Aerial Vehicle (UAV). The proposed transmission scheme in this paper used Orthogonal Frequency Division Multiplexing (OFDM) as its base. The common problems transmitting the video data are the long-time delay spread and Doppler spread since the UAV dynamically moves with high-speed movements. The UAV flight scenario can influence the channel parameters such as delay, Doppler, and different-phase. Therefore, these variable channel conditions are a challenge for OFDM-based communication systems. The initial experiment before improvement shows that a data link with 1.2 Mbps bandwidth which is enough for video streaming up to SD 480p quality, can be achieved if SNR is equal to or greater than 23 dB. Also, 100% packet data loss will occur if the SNR is equal to or less than 9 dB.
