Hierarchical 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. WebB. Review of Prior Work: Hierarchical Codebook Design In mmWave massive MIMO channel, there is usually one dominant line-of-sight (LOS) path and several secondary non-line-of-sight (NLOS) paths. Hierarchical beam training usually focuses on the efficient search of the dominant path by designing hierarchical codebook layer by layer.
