摘要：
Reversibility in the directivity in the event of transmission/reception through a multi-antenna system is well suitably compensated for by executing self-calibration. A branch is set to a reference branch, and a forward loopback transfer function and a backward loopback transfer function are acquired, whereby per-branch calibration factors are calculated. Subsequently, an other branch is set to a reference branch, and calibration factors are calculated in a similar manner. Then, the calibration factor for the reference branch is corrected in accordance with the secondly obtained calibration factor so that a calibration condition is satisfied.
