无人机测控系统Turbo-MAP译码方法

摘要

Unmanned Aerial Vehicle (UAV) data link in measurement and control system transmits all of the telemetry,scouting images and telecommand to ground control station. So it is the key point that improving the fight efficiency to keep higher quality communication on UAV data link. A Turbo-MAP decoding method in UAV measurement and control system is proposed and simulated after analyzing the parameters. The results show that it can ensure longer data packet which are used and interleaving depth which is increased ,and it can improve the decoding BER performance.%无人机测控数据链系统与地面控制站进行的是遥测数据、侦察图像及遥控指令的传输，因此，高质量的通信是确保无人机数据链发挥效能的关键技术之一。针对无人机信道的特点和要求，研究了无人机信道的Tur-bo-MAP译码模型，提出一种无人机测控系统Turbo-MAP译码方法，并针对各种参数条件进行了Matlab仿真。实验结果证明，该方法能够保证在发送数据的时候尽量使用长度较长的数据包且增加交织深度，并显著提升译码BER性能。
