| Abstract: |
| This paper analyses the UAV(Unmanned Aerial Vehicle) TT&C channel model, the gen
eration mechanism and characteristics of three kinds of small-scale-fading inclu
ding frequency selective fading, frequency selective fading and time selective f
ading, discusses anti-fading methods,and finally demonstrates OFDM,interleavin
g and coded modulation, and spatial diversity are potential anti-fading techniqu
es in UAV TT&C. |
