摘要
The present invention discloses a phase imbalance monitoring apparatus, an amplitude imbalance monitoring apparatus, as well as an apparatus incorporating the same. The phase imbalance monitoring apparatus is for use in an apparatus in which imbalance between an I branch signal and a Q branch signal in quadrature to each other is required to be monitored, and is characterized in comprising a preprocessing unit, for performing preprocessing on the I branch signal and the Q branch signal to extract essential information relevant to correlation of the signals; and a correlation unit, for performing correlation processing on the extracted essential information to learn of the phase imbalance between the I branch signal and the Q branch signal.
