JOINT BEAMFORMING METHOD AND SYSTEM FOR HETEROGENEOUS INTELLIGENT REFLECTING SURFACE SYSTEM, MEDIUM AND TERMINAL

Provided in the present invention are a joint beamforming method and system for a heterogeneous intelligent reflecting surface system, a medium and a terminal. The method comprises the following steps: acquiring the number of users participating in federated training and the number of reflection units contained in each intelligent reflecting surface; on the basis of the number of the users and the number of the reflection units, initializing a global federated model; in each training cycle, providing each user with the global federated model, so as to enable each user to update a local federated model by means of using the global federated model, and to train the local federated model by means of using a local data set, and aggregating the local federated models of all the users, so as to obtain an aggregated global federated model; and on the basis of the aggregated global federated model, predicting joint beamforming of a heterogeneous intelligent reflecting surface system. The joint beamforming method and
