“…The ISAC signal combining OFDM and LFM is proposed to improve the resolution of detecting long-distance targets, and the resolution is improved by increasing the timebandwidth product [39]- [42]. ISAC signal combining OFDM and phase coding reduces the PAPR [43]- [46]. To enhance the anti-interference capability of ISAC signal in the low SNR regime, ISAC signals combining OFDM and spread spectrum are proposed [47]- [50].…”

Integrated sensing and communication (ISAC) has the advantages of efficient spectrum utilization and low hardware cost. It is promising to be implemented in the fifth-generationadvanced (5G-A) and sixth-generation (6G) mobile communication systems, having the potential to be applied in intelligent applications requiring both communication and high-accurate sensing capabilities. As the fundamental technology of ISAC, ISAC signal directly impacts the performance of sensing and communication. This article systematically reviews the literature on ISAC signals from the perspective of mobile communication systems, including ISAC signal design, ISAC signal processing algorithms and ISAC signal optimization. We first review the ISAC signal design based on 5G, 5G-A and 6G mobile communication systems. Then, radar signal processing methods are reviewed for ISAC signals, mainly including the channel information matrix method, spectrum lines estimator method and super resolution method. In terms of signal optimization, we summarize peak-to-average power ratio (PAPR) optimization, interference management, and adaptive signal optimization for ISAC signals. This article may provide the guidelines for the research of ISAC signals in 5G-A and 6G mobile communication systems.

“…Signal energy sharing is an approach via emitting a signal to complete a variety of electronic warfare equipment functions simultaneously, i.e. to make a signal possess various signals’ functions [2–4]. In allusion to the Radcom system, when tracking or detecting targets, the transmission commands, the datum, and other signals are sent to the guided missile, the friend aircraft, and the ground command centre, which are in the covered areas of the bind to achieve communication function.…”
