Abstract: | This paper proposes an integrated sensing, energy, and communication (ISEAC) system that considers secure communication. In this system, the base station (BS) is serving as one legitimate single-antenna information receiver (IR) whose position is known and multiple single-antenna energy receivers (ERs) that are considered as eavesdroppers whose locations are unknown and need to be detected. First, we propose a framework for designing transmitter beamforming to maximize the system secrecy rate under the energy-harvesting constraint and the sensing constraints. Next, we study the beamforming design of the system under imperfect channel status information (CSI). For the non-convex equations in these two cases, we use semidefinite relaxation (SDR) and Taylor expansion to transform the problem to the convex form. Finally, the simulation results verify the effective performance of the proposed optimal beamforming design. |
