Abstract
A system and method for power control in a wireless transmitter. A power control loop includes a feed forward unit coupled to a data source, the feed forward unit processes a signal for transmission, a feedback unit coupled to the feed forward unit, the feedback unit generates a feedback signal representative of an output power level of the signal transmitted by the feed forward unit, a closed loop power control unit coupled to the feedback unit and to the feed forward unit, the closed loop power control unit generates an additive correction signal based on an error signal computed from the feedback signal and data provided by the data source or software instructions, and a ramp path power control unit coupled to the data source, the ramp path power control unit generates a multiplicative correction signal based on an additive correction signal and data provided by the data source.
