The network system also includes a number of mobile stations (MS) each having its own antenna array. The base station modulates a transmit signal directed to a MS with a transmit beamformer as specified by the controller. The MS equalizes a received signal with a receive beamformer. The controller is configured to calculate an outage probability of the MS based on statistical channel state information at the BS, for a given set of a transmit beamformer wk, a receive beamformer vk, and a predetermined threshold of a signal-to-noise-interference-plus-noise ratio (SINR) at the MS. The controller is also configured to obtain a solution set comprising a transmit beamformer wk and a receive beamformer vk. The controller is further configured to specify, based on the obtained solution set, the beamformers to be adopted."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Processing blind beamforming for multi-user multiple-input multiple-output (MU-MIMO) systems","description":"A wireless network system includes a base station (BS) having a number of array antennas and a controller.
