| 摘要 | Orthogonal Time Frequency Space (OTFS) possesses unique advantages in high-mobility communication scenar-ios due to its robustness against high Doppler frequency shifts, making it an ideal modulation technique for Integrated Sensing and Communication (ISAC) to achieve target sensing functionality. Current research on OTFS for target localization is primarily based on simulations, and the advantages of OTFS signals in target localization have not been fully exploited. Therefore, this paper proposes a three-ellipse positioning algorithm, combined with an off-grid channel estimation method, to achieve the OTFS signal target positioning function. We use the embedded pilot-assisted channel estimation scheme of OTFS to insert pilots, data symbols, and protection areas in the delayed-Doppler plane. Then, the delay and Doppler information of the channel are estimated by the pilot position in the received signal to obtain the physical properties of the channel, including distance, velocity, etc. The three-ellipse positioning algorithm is used to estimate the target position based on these channel parameters. Finally, we build a real communication scenario and our algorithm was experimentally verified by using a USRP-based software defined radio (SDR) platform, proving the effectiveness of our algorithm on the hardware platform. |
