| Zusammenfassung: | A calibration-less transmit beamforming apparatus and method are provided. In a wireless communication device that comprises a plurality of antennas, a gain block is provided in the front-end module associated with each antenna and the same gain block is used during transmit and receive operations. As a result, the transmit phase offset and receive phase offset for each antenna are made to be equal, thereby achieving conditions for transmit beamforming without the need for complex antenna calibration algorithms and hardware. |
