| 摘 要： | 描述了一种无人机通信信道模型。该模型由：视行分量;反射分量;散射分量三部分组成。根据已证实的测量结果和经验数据,给出了典型仿真值。对OFDM在无人机的3个主要状态下的误码率性能进行了仿真,并与OQPSK作了比较。仿真结果表明OFDM能有效克服由多径信道引起的码间干扰,比传统的单载波传输技术更适合无人机通信信道。

| Abstract: | A communication channel model of unmanned aircraft vehicle (UAV) was described. This channel is composed of a line-of-sight signal, a specular reflection and a diffuse multipath component. Based on published measurement results and empirical data, the typical simulation parameters were proposed. Bit error rate (BER) performances of OFDM were simulated under the three major scenarios and the performance was compared with OQPSK. The MATLAB simulation proves that OFDM can effectively combat Inter Symbol Interference (ISI) caused by multipath channel and is better suited to the UAV communication channel than the traditional single carrier transmission technique. |
