Abstract
A control unit (control device) () is configured to be connectable to radio units (-to-N), respectively, and each path unit () includes path units (-to-N) having a first input path (L) and a second input path (L). The first input path (L) is a path on which a corresponding DPD unit () is provided and through which a transmission baseband signal compensated for the non-linear distortion is input to a corresponding radio unit (). The second input path (L) is a path through which a transmission calibration signal for calibrating a path and amplitude deviation between the radio units () is input to the corresponding radio unit () without passing through the DPD unit ().
