论文摘要
在本文中，我们为正交频施加多路复用（OFDM）集成感应和通信（ISAC）系统开发了一个光束跟踪方案，该系统具有在毫米波（MMWave）频段中运行的混合数字模拟（HDA）结构。我们的跟踪方法包括一个受雷达信号处理技术启发的估计步骤，以及基于简单运动学方程的预测步骤。混合体系结构利用了预测的状态信息，只专注于感兴趣的方向，交易波束形成增益，硬件复杂性和多发达处理功能。我们在任意轨迹中进行的广泛模拟表明，所提出的方法可以从预测准确性和可实现的通信速率方面胜过最先进的光束跟踪方法，并且完全能够处理高度非线性的动态运动模式。
In this paper, we develop a beam tracking scheme for an orthogonal frequency division multiplexing (OFDM) Integrated Sensing and Communication (ISAC) system with a hybrid digital analog (HDA) architecture operating in the millimeter wave (mmWave) band. Our tracking method consists of an estimation step inspired by radar signal processing techniques, and a prediction step based on simple kinematic equations. The hybrid architecture exploits the predicted state information to focus only on the directions of interest, trading off beamforming gain, hardware complexity and multistream processing capabilities. Our extensive simulations in arbitrary trajectories show that the proposed method can outperform state of the art beam tracking methods in terms of prediction accuracy and consequently achievable communication rate, and is fully capable of dealing with highly non-linear dynamic motion patterns.
