Abstract :
The wireless communication in the Unmanned Aerial Vehicle (UAV) data link faces serious multi path fading, which leads to frequency-selective fading and inter-symbol interference and affects the quality of data transmission. Single Carrier Frequency Domain Equalization (SC-FDE) is an effective method to mitigate the influence of multipath fading. Frame structure is essential in wireless communication system, and the design of frame affects synchronization and channel-estimation. The paper introduces SC-FDE system firstly, and then the design of frame structure in SC-FDE and orthogonal frequency division multiplexing (OFDM) is given. Many researches have been made in this area. In this paper, we present several frame structures. The brief structures and their advantages are given.
