| 摘要 |
The present invention relates to a method, system, apparatus, and computer pro-gram product for transmitting or receiving a plurality of time-duplexed transmission signal components via respective transmission or reception chains and respective antenna elements of a smart antenna system. A calibration signal is temporarily coupled into or from the transmission or reception chains via a selected one of the transmission or reception chains by using a portion of the transmission signal components, and a calibration signal parameter, influenced by said transmission or reception chains, is measured relative to a selected one of the transmission or reception chains. Then, a beamforming process of said smart antenna system is calibrated in response to a result of the measuring. |
