Assignee: COHERE TECHNOLOGIES, INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A wireless communication device, comprising:
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,
wherein the antenna subsystem comprises a Luneburg antenna,
wherein a hemispherical shape of the Luneburg antenna is formed by joining or stitching a plurality of tiles to minimize surface discontinuities,
wherein the antenna subsystem is configured to transmit an output signal of the precoding subsystem to multiple wireless stations using multiple beams,
wherein a beamwidth of at least one of the multiple beams transmitted from the Luneburg antenna is smaller than a width of a tile of the plurality of tiles,
wherein the precoding subsystem is configured to perform a precoding operation on an input signal from the feed port, and wherein the precoding operation maximizes a desired signal level to interference ratio of transmissions to the multiple wireless stations.
