A new codebook design scheme for fast beam searching in millimeter-wave communications

摘要

To overcome imperfection of exhaustive based beam searching scheme in IEEE 802.15.3c and IEEE 802.11ad and accelerate the beam training process, combined with the fast beam searching algorithm previously proposed, this paper proposed a beam codebook design scheme for phased array to not only satisfy the fast beam searching algorithm's demand, but also make good use of the advantage of the searching algorithm. The simulation results prove that the proposed scheme not only performs well on flexibility and searching time complexity, but also has high success ratio.
