To predict the channel capacity of mobile users and appropriately allocate user resources in multiple-input-multiple-output systems, a channel capacity prediction method based on dynamic mode decomposition (DMD) is proposed. Meanwhile, a selective normalized dynamic mode decomposition method based on empirical mode decomposition (ESN-DMD)is proposed to optimize the system.. The simulation results show that the DMD algorithm is only suitable for the prediction of user signals at low moving speed and low complex, while the ESN-DMD algorithm can adapt to the prediction of channel capacity of users with different moving speeds. © 2021, Editorial Department of Journal of Beijing University of Posts and Telecommunications.
