论文摘要
在本文中，提出了一种适用于Terahertz（THZ）无线系统的新型分层横梁进行方法。主要思想是使用多分辨率代码簿采用基于预测的算法，以减少跟踪的开销并提高其鲁棒性。根据飞行员的平均数量和平方误差（MSE）评估算法的效率，并将其与快速通道跟踪（FCT）算法的相应性能进行比较。我们的结果强调了与FCT相比，在跟踪效率低下的效率方面，提出的方法的优越性。
In this paper, a novel hierarchical beamtracking approach, which is suitable for terahertz (THz) wireless systems, is presented. The main idea is to employ a prediction based algorithm with a multi-resolution codebook, in order to decrease the required overhead of tracking and increase its robustness. The efficiency of the algorithm is evaluated in terms of the average number of pilots and mean square error (MSE) and is compared with the corresponding performance of the fast channel tracking (FCT) algorithm. Our results highlight the superiority of the proposed approach in comparison with FCT, in terms of tracking efficiency with low overhead.
