OFDM will be a key technology in next mobile communications, and has potential applications in unmanned aerial vehicle (UAV) telemetry, so a UAV telemetry system based on OFDM is implemented on basis of analyzing its advantages in this paper. Firstly, the system scheme is presented. Then the baseband transmitter and receiver are designed in detail. All of OFDM baseband processing algorithms are accomplished in FPGA. The baseband test is developed, and the test result of PAPR is 12 dB, and the Eb/N0 lose is about 1 dB compared with the theoretical value. Finally, the UAV telemetry system is built, and the flying experiments are done. The experiment results show that OFDM is available technology in UAV telemetry.
