System and method for synchronization, power control, calibration, and modulation in communication transmitters |
摘要 |
A system is provided for processing a communication signal including a baseband amplitude component and a baseband phase component. The system includes an amplitude predictor configured for closed-loop pre-distortion of a baseband amplitude component, an amplitude lookup table configured for open-loop pre-distortion of the baseband amplitude component, and an amplitude interpolator configured to build up the amplitude lookup table during a closed-loop calibration period. The system also includes a phase predictor configured for closed-loop pre-distortion of a baseband phase component, a phase lookup table configured for open-loop pre-distortion of the baseband phase component, and a phase interpolator configured to build up the phase lookup table during a closed-loop calibration period. |
