摘　　要：无人机数据链系统与地面控制站进行的是遥测数据、侦察图像和遥控指令传输,因此高质量的通信是确保无人机数据链发挥效能的关键。针对无人机信道的特点和要求,研究分析了无人机信道的统计模型,重点分析了影响Turbo码性能的一些主要因素,采用硬件描述语言VerilogHDL实现了Turbo码编译码器的FPGA设计。实验结果表明,在纠错能力范围内,该设计方案能够正确纠错并译码,并且具有较高的译码速率,提高了无人机数据链的通信质量和抗干扰性能。Unmanned Aerial Vehicle(UAV)data link system transmits all of the telemetry,reconnaissance images and telecommand to ground control station.So it is the key point that improves the fight efficiency to keep higher quality communication on UAV data link.In this thesis,according to the characteristics of UAV communication channel,the model of UAV channel is studied after parameter analysis.And several major factors affecting the Turbo coding performance are analyzed.Finally the turbo coder and decoder are implemented based on FPGA using Verilog HDL.The simulation result indicates that proposed solution can correct the error bits exactly within the range of error-correcting capability,and it has the advantage of high-speed decoding.Expected effect is realized.This design scheme improves the communication quality and the anti-jamming capability.
