Sub-array based hybrid precoding design for downlink millimeter-wave multi-user massive MIMO systems
Abstract: In this paper, we investigate the downlink of millimeter-wave multi-user massive MIMO systems, and propose a hybrid precoding scheme based on a sub-array architecture to achieve a better ...
Abstract: We propose a directive antenna for borehole radar using a horizontally polarized wave in a vertical borehole. This antenna is an array of several horizontal loop antennas, arranged ...
