Block Turbo Coded OFDM Scheme and Its Performances for UAV High-speed Data Link

We investigate the case of Block Turbo Codes (BTCs) combined with Orthogonal Frequency Division Multiplexing (OFDM) technique for Unmanned Aerial Vehicles (UAVs) highspeed data link. Considering the UAV channel with time-varying and multipath fast fading characteristics, a 3-path UAV channel model is developed, which can be readily implemented under simulation condition. Two typical communication scenarios are studied in the basis of various UAVs flight situations. Simulations are conducted to evaluate the BER performances of BTC-OFDM over UAV channel. Comparisons among convolutional coded OFDM, turbo coded OFDM and the proposed scheme are also provided. Numerical results show that BTC-OFDM scheme can serve as an optimal solution for UAV high-speed data link even in the worst scenario.
