Abstract:

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 circuit, demodulation circuit 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 115.2kbps, the communication bit error rate is less than 10^-5.
