Abstract
A wireless communication device includes a feed port comprising multiple input feeds, a precoding subsystem that is electrically connected to the feed port; and an antenna subsystem electrically connected to the precoding subsystem. The antenna subsystem is configured to transmit an output signal of the precoding subsystem to multiple wireless stations using multiple beams. The precoding subsystem is configured to perform a precoding operation on an input signal from the feed port, wherein the precoding operation maximizes a desired signal level to interference ratio of transmissions to the multiple wireless stations.
