摘　　要：针对无人机宽带数据链地空高速数据传输需求,基于软件无线电技术,提出了一种2.0 Gb/s高速调制解调器的实现方法。从总体角度阐述了设计原理和实现架构,介绍了相关的软硬件关键技术,通过软硬件设计相结合,解决了速度需求与现有硬件最高运行时钟有限的矛盾。通过测试,验证了该方法的可行性。相比传统无人机地空调制解调器,所提方法传输速率提高近10倍,带宽利用率提高2倍以上。To meet the requirement of ground-to-air high speed data transmission of UAV broadband data link,a 2.0 Gb/s high speed modem based on software radio technology is developed.The principle and implementation architecture of this design is described from a general perspective,then the design and implementation of key software and hardware is introduced,and the contradiction between the speed demand and limited maximum running clock of existing hardware is solved based on a combination of software and hardware design.The feasibility of the scheme is verified by testing.As compared with traditional modem for UAV ground-to-air high speed data transmission,the transmission rate is increased by nearly 10 times,and the bandwidth utilization more than 2 times.
