Integrated Sensing and Communications Enabled Low Earth Orbit Satellite Systems
Extreme crowding of electromagnetic spectrum in recent years has led to the challenges in designing sensing and communications systems. Both systems require a broad range of bandwidth, thus resulting in competing interests in exploiting the spectrum. Efficient spectrum and hardware utilization have led to the emergence of integrated sensing and communications (ISAC) systems, which have recently emerged as a candidate 6G technology. In particular, we provide potential techniques, namely the opportunistic ISAC and optimized ISAC. Rate-splitting multiple access (RSMA) is highlighted as an optimized ISAC technique for LEO-ISAC systems due to its effectiveness in simultaneously managing interference and enabling better communication-sensing trade-off performance.
