Hierarchical codebook
Web13 de abr. de 2015 · 5. Hierarchical Codebook of SURF. In our system, the variability of pedestrians is represented by learning, in the first step, a codebook of local head appearances. 5.1. Hierarchical Codebook Generation. Clustering is a common method for learning a compact and discriminative codebook. WebTo address the challenge of this hardware complexity, we propose in this paper an approach to design a multiresolution hierarchical codebook to meet parallel multistream data based on the physical design via hybrid analog/digital architecture with low complexity, i.e., 2-bit phase state and few numbers of RF chains.

Web21 de set. de 2024 · Beam training is an effective way to acquire channel state information (CSI) for the XL-RIS assisted system. Existing beam training schemes rely on the far-field codebook, which is designed based on the far-field channel model. However, due to the large aperture of XL-RIS, the user is more likely to be in the near-field region of XL-RIS.
