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.

Abstract: A wireless communication circuit and an electronic device are provided. The wireless communication circuit used for an electronic device includes a wireless transceiver unit used to generate a transmitting signal, an impedance matching unit electronically coupled to the wireless transceiver unit, a coupling unit and a system grounding surface. The impedance matching unit includes at least one impedance, the impedance matching unit is used to convert the transmitting signal to a feeding signal according to the impedance value of at least one impedance. The coupling unit is electronically coupled to the impedance matching unit, to radiate the energy of the feeding signal. The system grounding surface is used to transmit a first electromagnetic wave signal via resonance on the plane of the system grounding surface after receiving the energy of the feeding signal.
