Abstract
A power control loop includes a feed forward unit 301 coupled to a data source, the feed forward unit 301 processes a signal for transmission, a feedback unit 302 coupled to the feed forward unit 301, the feedback unit 302 generates a feedback signal representative of an output power level of the signal transmitted by the feed forward unit 301, a closed loop power control unit 303 coupled to the feedback unit 302 and to the feed forward unit 301, the closed loop power control unit 303 generates an additive correction signal based on an error signal computed from the feedback signal and data provided by the data source, and a ramp path power control unit 304 coupled to the data source, the ramp path power control unit 304 generates a multiplicative correction signal based on an additive correction signal and data provided by the data source.
