Abstract
Emerging literature has shown that deploying reconfigurable intelligent surface (RIS) can remarkably promote integrated sensing and communication (ISAC) system’s performance. Meanwhile, the emerging novel beyond-diagonal (BD)-RIS architecture has manifested its superior beamforming capability over the conventional diagonal RIS. This paper investigates utilizing fully-connected BD-RIS to improve ISAC system’s throughput while ensuring sensing quality, By utilizing majorization-minimization (MM) and penalty-dual-decomposition (PDD) method, we develop an efficient algorithm to tackle the orthogonality condition and non-convex quartic inequality involving BD-RIS. Numerical results demonstrate the effectiveness of our solution and the benefit of BD-RIS deployment in ISAC network.
