摘要 面向复杂机载环境下大量电子设备控制信号和数据信息的传输需求,研究基于机载电力线的载波通信方案和设计实现方法,进行原理开发验证和应用测试;论文研究基于FPGA的机载电力线载波通信系统中调制解调模块设计方法,设计的2FSK调制解调模块包含调制通路、解调通路和控制电路3个部分,给出了每个部分内部具体子模块的设计原理和实现方法,并针对子模块功能分别进行了仿真和实验验证,最终结合所开发的电力线载波通信系统进行通信性能测试,结果表明了文章设计的调制解调模块的正确性,在通信波特率115.2 kbps情况下,可实现通信误码率低于10^(-5)。 Facing the transmission requirements of electronic control and data signals in airborne environment,the carrier communication scheme based on airborne power line is studied,developed,verified and tested.This paper studies the design method of modulation and demodulation module in airborne power line carrier communication system based on FPGA.The 2FSK modulation and demodulation module includes three sub modules,which are modulation pathways,demodulation pathways and control circuit.The design principle and implementation method of the module are given,and the simulation and experimental verification are completed.The results show that the modulation and demodulation module designed in this paper is correct.When the communication baud rate is 115.2 kbps,the communication bit error rate is less than 10^(-5).
