| 摘要 |
Certain aspects of the present disclosure provide an apparatus for wireless communications. The apparatus comprises an interface configured to output a first signal for transmission via at least one first antenna, to output a second signal for transmission via at least one second antenna, to receive the transmitted first signal via the at least one second antenna, and to receive the transmitted second signal via the at least one first antenna. The apparatus also comprises a processing system configured to measure a phase of the received first signal and a phase of the received second signal, to determine a phase correction for the at least one first antenna based on the measured phase of the received first signal and the measured phase of the received second signal, and to shift a phase of a transmit signal by the phase correction, wherein the interface is configured to output the transmit signal for transmission via the at least one first antenna after the transmit signal is phase shifted. |
