摘　　要：针对L频段数字航空通信系统接收机DME信号干扰抑制算法缺乏真实验证平台这一问题,利用软件无线电技术搭建L⁃DACS1的原型系统。按照L⁃DACS1系统前向链路的技术参数和超帧结构,设计实现了基于Yun SDR320和Matlab的L⁃DACS1系统前向链路发射机和接收机的原型构建,在真实的无线信道环境下实现信号的发送与接收。测试结果表明,所设计的L⁃DACS1系统前向链路平台符合系统规范、工作稳定,该平台可以用作未来DME干扰抑制算法的验证平台。In view of the fact that there is no real verification platform used for the DME(distance⁃measuring equipment)signal interference suppression algorithms of the L⁃band digital aeronautical communication system 1(L⁃DACS1)receiver,a prototype system of L⁃DACS1 is built with software radio technology.In accordance with the technical parameters and superframe structure of the forward link of L⁃DACS1,a prototype of the transmitter and receiver of the L⁃DACS1 forward link based on Yun SDR320 and Matlab is designed and implemented,so as to transmit and receive the signals in the real wireless channel environment.The test results indicate that the designed forward link platform for L⁃DACS1 complies with the system specifications and can operate stably.Therefore,this platform can be used as the verification platform for DME interference suppression algorithms in the future.
