Receiver with multi-tone wideband I/Q mismatch calibration and method therefor |
摘要 |
In one embodiment, a method provides multiple-tone wideband I/Q mismatch calibration. A plurality of calibration frequencies is selected within a channel. A calibration tone is applied to the channel at each of the plurality of calibration frequencies. An I/Q mismatch is estimated at each of the plurality of calibration frequencies. An n-th order filter is constructed to compensate received signals relative to the estimated I/Q mismatch related to each calibration frequency.
