Webto estimate different MPCs, we use dynamic hierarchical codebook which is updated according to the estimated MPCs. To summarize, our contribution mainly includes: 1) A general-ized hierarchical codebook design method is firstly proposed. 2) Then based on this method, we propose a beam training method which dynamically updates the … WebIn this paper, we propose two basic criteria for the hierarchical codebook design, and devise an efficient hierarchical codebook by jointly exploiting sub-array and …
WebThe evaluation of the codebook distortion intro-duced in each cluster is used to stop the procedure on few levels, exploiting the dependency relationships between clus-ters. Finally, the user can navigate through summaries at each hierarchical level and then decide which level to adopt for eventual post-processing. Web1 de dez. de 2024 · The advantage is that the hierarchical search method is time efficient and can achieve high detection rates when identifying a virtual MPC path. The application of hierarchical codebook applies to MPCs with sufficiently large distances between them, avoiding the fact that two MPC paths in the same beam are estimated.
