چکیده
In this paper, an efficient scheduling technique for multiuser MIMO downlink with block diagonalization precoding in millimeter waves channel is presented. The scheduling technique is based on employing hybrid DE/EPSO optimization method to maximize the sum rate capacity for selected number of users for outdoor cellular systems. The proposed scheduling scheme achieves almost similar capacity performance to the optimum exhaustive search algorithm and compared with classical genetic algorithm technique. In this paper, block diagonalization beamforming performance is considered for different number of mobile users and different numbers of antennas at the receivers under correlated millimeter wave channel model.
