System and method of beamforming with reduced feedback |
摘要 |
A system and method of beamforming may reduce feedback requirements. In some implementations, a beamforming technique may employ a diagonal matrix as a beamforming matrix along with a stream-to-transmit antenna mapping matrix. In some antenna phase beamforming strategies, a diagonal beamforming matrix in which the diagonal elements have a constant magnitude may be employed. Accordingly, a beamforming system may be utilized with few feedback information bits being transmitted from the beamformee; such a system may also minimize or eliminate power fluctuations among multiple transmit antennae. |
