Ranging Method with Integrated Sensing and Communication Signals for UAV Cluster
Space-air-ground access integrating,integrated sensing and communication(ISAC)will be the key capabilities in 6G.This paper studies an SC-FDE ISAC signal framing method in UAV networking to meet the requirement of communication-aided sensing based on the communication signals.Additionally,the high-precision ranging methods for UAV clusters with 4 and 2 samples per symbol are proposed to improve the cooperative localization performance in the UAV cluster network.After extensive simulations,we found that these two ranging methods could achieve a performance of RMSE=0.1 m at SNR=10 dB.Furthermore,the 2 samples per symbol ranging method outperforms the 4 samples method,and gets closer to the CRB theoretical performance bound.
