N2  - In this paper, we propose a constructive interference (CI)-based precoding scheme and extend the proposed precoding scheme from the symbol level to the block level for multiple-input multiple-output (MIMO) integrated sensing and communication (ISAC) systems. The illumination power of radar is maximized under communication CI constraint. Since the optimization objective function is not convex, we use succesive convex ap-proximation (SCA) method to solve the proposed optimization problem. Furthermore, we formulate the dual problem of the convex subproblem in SCA method. It is a simple quadratic programming (QP) problem and can be efficiently solved. The simulation results show that the proposed CI-based precoding design has significant advantages in enhancing the ISAC performance with acceptable computational complexity.
