Low-complexity tuning of pinching-antenna systems for integrated sensing and communication
This work addresses interference reduction in wireless systems for applications like autonomous vehicles or IoT, but it appears incremental as it builds on existing pinching antenna systems with a new tuning method.
The paper tackles the problem of enabling simultaneous sensing and data transmission with minimal interference in integrated sensing and communication systems using pinching antenna systems, proposing a bi-partitioning strategy that achieves a significantly larger sensing-communication rate region compared to baselines at no noticeable cost.
Pinching antenna systems (PASSs) can dynamically adapt their transmit and receive arrays for sensing and communication in wireless systems. This work explores the potential of PASSs for integrated sensing and communication (ISAC) by proposing a novel PASS-aided ISAC design, in which pinching locations are adaptively adjusted to enable simultaneous sensing and data transmission with minimal interference. The proposed design introduces a bi-partitioning strategy that allocates sensing power and tunes pinching locations with remarkably low computational complexity, allowing dynamic PASS tuning at high update rates. Numerical results demonstrate that the proposed approach achieves a significantly larger sensing-communication rate region compared to baseline designs at no noticeable cost.
