Integrated Communication and Measurement System with BOC-Assisted OFDM

For unmanned aerial vehicles (UAVs), high-precision measurement and high-speed communication are necessary to realize flight operational missions. In this paper, we propose an integrated system in a Doppler frequency offset environment. The combines orthogonal division multiplexing (OFDM) modulation with binary carrier (BOC) formulate OFDM+BOC composite signal through power control. High-precision is achieved BOC modulation, high data transmission OFDM modulation. Furthermore, the tracked by adopted assist demodulation of signal. This substantially decreases impact on Moreover, ranging error within 10−2, maximum 2 Hz.
