Abstract

The constructive interference (CI) based symbollevel precoding (SLP) design for integrated sensing and communication (ISAC) systems is investigated in this paper. The minimum communication scaling factor among the users is maximized under radar performance constraint and power constraint through optimizing the transmit signal. In order to solve the proposed optimization problem, two groups of approximate feasible domains are adopted to transform the optimization problem into convex. The simulation results show that the proposed SLP design based on symbol scaling has significant advantages in enhancing the communication performance under the condition that the radar performance satisfy the requirements. And compared with the previous SLP schemes in ISAC system, the computational complexity of the proposed schemes can be reduced significantly.
