Abstract

This work is concerned with integrated sensing, communication, and computation (ISCC) in uplink orthogonal frequency division multiplexing (OFDM) systems, wherein multiple devices perform target sensing and over-the-air computation (AirComp) simultaneously. We aim to minimize the computational mean squared error (MSE) by jointly optimizing the transmitting vector and the aggregation vector. To tackle the non-convexity of the formulated problem, we develop a two-phase iterative algorithm. Simulations demonstrate that the proposed algorithm can achieve a better sensing-computation trade-off.
