Abstract
A wireless transceiver system includes a transmitter and a receiver. The transmitter includes a digital processor and a self-correction modulator coupled to the digital processor, wherein based upon a calibration correction assessment of an in-phase (I) signal and a quadrature (Q) signal received from the digital processor, the self-correction modulator generates a calibrated modulated signal. The self-correction modulator includes a core modulator and a calibration correction unit. The calibration correction unit is configured to correct an output of the core modulator based upon the calibration correction assessment. The calibration correction unit includes a calibration processing unit and a calibration modulator, wherein the calibration processing unit provides correction quantities that are used to program the calibration modulator to provide the self-corrected modulated signal.
