标题： Pinching-Antenna Systems (PASS)-based Indoor Positioning

摘要： 定向天线（PA），一种与介电粒子集成的柔性波导，智能地重建视距信道。 利用其几何确定性模型和米级重建，PA系统（PASS）被应用于上行链路室内定位。 在本文中，首先提出了基于PASS的上行链路定位系统模型。 提出了一种基于PASS的接收信号强度指示（RSSI）方法，以测量用户到每个PA的距离，该方法高效且适用于PASS。 设计了基于PASS的加权最小二乘（WLS）算法来计算用户的二维坐标。 从我们的结果中可以得出几个关键观察：i）波导上的PA越多，定位精度和鲁棒性越高。 ii）当PA的数量超过某个阈值时，性能增益变得微不足道。 iii）PA之间和附近的用户位置产生更精确的定位精度。 显示英文摘要

摘要： Pinching antenna (PA), a flexible waveguide integrated with dielectric particles, intelligently reconstructs line-of-sight channels. Utilizing its geometric deterministic model and meter-level reconstruction, PA systems (PASS) are applied to uplink indoor positioning. In this paper, the uplink positioning system model for PASS is firstly proposed. A PASS-based received signal strength indication (RSSI) method is proposed to measure the distance from the users to each PA, which is efficient and suitable for PASS. PASS-based weighted least squares (WLS) algorithm is designed to calculate the two-dimensional coordinates of the users. Several critical observations can be drawn from our results: i) More PAs on the waveguide improves the positioning accuracy and robustness. ii) When the number of PAs exceeds a certain threshold, the performance gain becomes marginal. iii) User locations between and near PAs yield superior positioning accuracy.
