Abstract: By combining the advantages of integrated sensing and communication (ISAC) and over-the-air computation (AirComp), integrated sensing, communication, and computation over-the-air design is proposed, where the multi-antenna beamforming designs for both radar sensing and AirComp are jointly optimized to maximize the AirComp accuracy while guaranteeing the sensing accuracy. T Through the simulation verification and the comparison with the traditional beam configuration, the design can effectively realize the radar perception and air computing simultaneously, and significantly improve the spectrum efficiency.

Keywords: integrated sensing and communication; over-the-air computation; beamforming
