A first channel matrix can be transformed into a transformed second channel matrix. The first channel matrix can be a channel from a transmitter array of antennas of the transmitting device to at least one receiver antenna of a receiving device. A precoding matrix can be determined that maximizes the capacity for the transformed second channel matrix subject to a power constraint of the precoding matrix. The channel capacity maximizing precoding matrix for the transformed second channel matrix can be converted into an optimal precoding matrix for the first channel matrix. A signal can be received for transmission. The optimal precoding matrix can be applied to the signal to generate a precoded signal for transmission over a physical channel. The precoded signal can then be transmitted."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for beamforming with coupled antennas","description":"A method and apparatus provide beamforming with coupled antennas.
