Abstract
A system, method and computer program product that uses an expected output power level to compensate for slowly changing unintentional power fluctuations in a signal transmission system such that the actual transmitted power matches a calculated desired transmit power. Digital expected power data is sampled and filtered to generate an expected output power level. Actual output data is sampled and filtered to generate an actual output power level. A comparator periodically compares the expected output power level to the actual output power level. Preferably, the comparator first removes a correction value from the actual output power level that was added to the transmit signal to correct for unintentional power fluctuations. The resultant ratio or difference is sent to a correction module which generates a correction value therefrom. The correction value is converted to a dB quantity and added to existing correction values.
