Abstract: The integrated sensing and communication (ISAC) is envisioned as a key technique for B5G/6G networks. Pilot-based ISAC design, i.e., leveraging the pilot or reference signal (RS) in communication system to achieve wireless sensing, is well compatible with the current OFDM communication system. In this talk, the principle of pilot-based OFDM ISAC is first introduced. Then, to address the critical problem of inter-symbol-interference (ISI) in OFDM long-range sensing, we delve into a solution that focuses on pilot signal design and processing to achieve ISI-resistant OFDM ISAC. Two distinct designs have been developed for the IEEE 802.11 ad-based radar sensing system and the 5G ISAC system, respectively. Both cases show the advantages of incorporating zero-power pilot signals in the pilot design for ISAC, offering effective solutions to long-range sensing. After that, an implementation of integrating bistatic sensing into B5G/6G system via RS at mmWave band is developed, where the system calibration, algorithm design, and experiment measurement are presented. The experiment results show that accurate localization, tracking, and behavior recognition can be achieved for multi-target sensing via pilot-based sensing.
