Techniques are provided that utilize information on the characteristics of the transmitted signal to improve the accuracy of the I/Q imbalance estimation and correction. These techniques can be used to achieve improved image rejection performance over existing solutions, through the use of signal conditioning, windowing and the use of statistical information on the received signal. A number of techniques aimed at improving the accuracy of the I/Q imbalance estimation/correction are presented, including different modes of I/Q imbalance estimation and I/Q imbalance correction in the presence of a complex IF filter in the transceiver. The processing is performed mostly in the DBB in order to be area/power efficient. |
