摘要：
This letter investigates the hybrid beamforming architecture design for MIMO network, where the connection between each antenna and each radio frequency chain is controlled by a switch. The optimization of the switch-controlled connection state vector is studied for maximizing the energy efficiency of the system. The problem of connection-state vector design is transformed into a single-variable optimization problem, and the optimal hybrid beamforming architecture is derived. Numerical examples validate the effectiveness of the proposed scheme.
