METHOD AND DEVICE FOR MAINTAINING AVERAGE POWER OF A BASEBAND SIGNAL

摘要

A method (200) and device maintains constant average power of a baseband signal. The baseband signal to be power amplified is received (202) into a processing device that measures (204) a first average power of the baseband signal. Peak reduction is performed (206) on the received baseband signal. A second average power of the baseband signal is measured (208) after peak reduction. Gain compensation is determined (210) based on the difference between the first and second average power measurements. The gain compensation is applied (212) to the baseband signal after the peak reduction in order to maintain a substantially constant average power of the baseband signal.
