摘要：A calibration method for a base station removes distortion in traffic signalsincurred in transmit paths of the base station. The transmit paths are coupled to an

antenna array for transmitting the traffic signals in a wireless network. The methodincludes conditioning a traffic signal to reduce a correlation with another traffic signalbefore the traffic signals enter the transmit paths. For each of the traffic signals, animpairment estimation is performed based on the traffic signals captured beforeentering the transmit paths and the traffic signals captured before entering the antennaarray. An approximate inverse of the impairment estimation is applied to each of thetraffic signals before the traffic signals enter the transmit paths.
