Abstract
The proposed method improves dynamic range utilization of the ADC unit by adjusting the amplifier gain and a reference gain level used to compensate the amplifier gain adjustment, based on a saturation status of the ADC unit. An update of the reference gain level is performed according to the gain change of the analog amplifier of the received signal and the recent ADCs saturation status. This provides a technical advantage by ensuring that the decoded signal remains steady when the amplifier gain is adjusted, thus maintaining signal integrity. This may help to achieve a more or less steady output in all circumstances. Resulting therefrom, the signal to be decoded is kept constant. This may be useful, when the received signal is strong and the ADC unit is saturated despite adaptation of gain.
