N2 - Implementing integrated sensing and communication (ISAC) technique to construct perceptive mobile network (PMN) in existing communication networks has become a research hotspot. In this paper, we investigate the issue of cooperative ISAC (Co-ISAC) of multiple base stations (BSs). To avoid the impact of inter-cell interference (ICI) on CoISAC in joint transmission, the orthogonal frequency division multiplexing (OFDM) signals are encoded with space-time block coding (STBC) codeword by each cooperative BS in a distributed manner. Correspondingly, we propose an distributed STBCOFDM sensing processing scheme to simultaneously obtain both monostatic and bistatic sensing information. A novel sensing information fusion scheme is proposed to facilitate more accurate sensing. Numerical results show that with the employment of distributed STBC-OFDM signals, the proposed processing scheme can obtain and distinguish monostatic and bistatic observations, and the sensing information fusion scheme can effectively improve positioning accuracy.
