Under this setting, we jointly optimized the passive beamforming at STAR-RIS and the active beamforming at base station to minimize the Cram茅r-Rao bound (CRB) used to estimate the sensing target's two-dimensional direction of arrivals, while being constrained by the lowest signal-to-...
To this end, we consider secure symbol-level precoding design in RIS-aided ISAC systems. We maximize the user's signal-to-noise ratio (SNR) and Cramer-Rao bound (CRB) under the constraints of system power, constructive interference (CI) and security. The objective function is non-...
