The invention discloses a intelligent steel-oriented large-scale MIMO (Multiple Input Multiple Output) hybrid precoding method and device. The method comprises the following steps: constructing an analog precoding model and a digital precoding model; wherein the analog precoding model is a deep neural network model, and the digital precoding model is a generative adversarial network model; respectively training the analog pre-coding model and the digital pre-coding model; wherein the training data of the digital pre-coding model is a pure digital pre-coding matrix; obtaining channel state information between each antenna sub-array to be pre-coded and the corresponding user; based on the acquired channel state information, generating an analog pre-coding matrix by using the trained analog pre-coding model; and generating a digital pre-coding matrix by using a generator in the trained digital pre-coding model. According to the invention, the deep learning method is utilized to realize hybrid precoding, and the
