摘　　要：针对传统无人机测控链路中传输带宽、数据速率以及处理增益三者之间相互制约、帧结构复杂、抗干扰和多址能力较弱的缺点,研究并实现了基于高效编码扩频的无人机测控链路。该链路能够在12MHz信道带宽下同时传输20kHz低速数据和1MHz高速数据,具有较高的频带利用率和简单清晰的帧结构,实现了一站多机和一机多站,并且引入Turbo码,使得高速数据的处理增益高达33dB,具有较强的抗干扰性能。Aiming at the shortcomings that the restriction between the transmitting bandwidth, data speed and process gain, complex frame structure, weak anti -jamming and multiaddress performance in traditional unmanned aerial vehicle（UAV） TT＆C channel, the UAV TT＆C channel based on high efficient coded - spread spectrum is studied and realized. This channel can transmit low speed data at 20 kHz and high speed data at 1 MHz at the same time, the utilization is high,the frame structure is easy and clear, the one - plane - multi - station and one - station - multi - plane is realized, furthermore, the Turbo code is intro- duced to make the process gain as high as 33 dB, the anti -jamming performance is high.
