Abstract:
The present example provides for adaptive preset gain control. Adaptive Preset gain control may initially utilize calibration look up table values to initially set a power amplifier's gain. Subsequent additional corrections are determined and an adaptation look up table is created and applied to bring operation within tolerance. To maintain the amplifier within tolerance additional corrections may also be determined and added to the Adaptation Look Up table. In an alternative example the Calibration Look Up Table may be omitted, with a first transmission through the power amplifier acting as a training event. The Adaptation Look Up Table, may, by storing the last corrections form a history of prior operation which may be used as built in test to indicate potential system failures.
