Abstract: A codebook generation method and an electronic apparatus are provided. The codebook generation method includes: collecting a plurality of pieces of electric field information of a plurality of antenna units in at least one millimeter-wave antenna module based on an initial codebook; correspondingly generating a full chain codebook (Full Chain Codebook) based on the electric field information; then, extendedly generating a sub chain codebook (Sub Chain Codebook) based on the full chain codebook; and finally generating, based on the full chain codebook and the sub chain codebook, an optimized codebook (Optimized Codebook) by using a power saving algorithm or a cumulative distribution function 50% gain loss algorithm. Therefore, the electronic apparatus using the optimized codebook is more excellent in power saving efficiency and overall efficiency performance.
