LTE 표준 기반 상용 무인기 신호 복호화

초록

This paper presents a decoding method for signals transmitted between DJI commercial unmanned aerial vehicles (UAVs) operated in modern warfare and their controllers. This approach is significant because it enables obtaining information that can be utilized to counter enemy UAVs. Since the protocol of the target signals, Ocusync, has an LTE-like transmission structure, the decoding procedure is described based on the 3GPP LTE standard. The performance of the proposed decoding method was validated using Cyclic Redundancy Check (CRC) across a signal-to-noise ratio (SNR) range of 0 dB to 30 dB, demonstrating the effectiveness of the proposed method.
