Abstract

This letter presents a novel framework for integrated sensing and communication in WLAN systems. The proposed approach adapts multi-user multi-input multi-output precoder of Wi-Fi systems to enable simultaneous communication and sensing and simplifies power allocation between both tasks as an independent optimization problem while requiring minimal software upgrades. A flexible power allocation method optimizes signal-to-noise-plus-interference-ratio (SINR) balancing for users and targets, accommodating trade-offs between communication and sensing. Numerical results demonstrate the framework’s effectiveness in achieving balanced SINR and enhancing integrated sensing and communication (ISAC) performance.

具有解耦波束形成和功率分配的WLAN可持续ISAC

本文提出了一种用于WLAN系统集成传感和通信的新框架。该方法适应Wi-Fi系统的多用户多输入多输出预编码器，实现同时通信和传感，并将两个任务之间的功率分配简化为一个独立的优化问题，同时需要最少的软件升级。灵活的功率分配方法优化了用户和目标的信噪比（SINR）平衡，适应了通信和传感之间的权衡。数值结果表明，该框架在平衡信噪比和提高集成传感与通信（ISAC）性能方面是有效的。

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
