SYSTEMS AND METHODS FOR GAIN AND OFFSET CONTROL

摘要

The method for setting the initial gain and offset for the initial automatic gain and offset control (AGOC) is described. That way, by performing a binary search through the set of the fixed gain level while the offset is fixed, the signal is analog-to determining a gain level that does not unsaturated or supersaturated input to digital converter (ADC) - to- do. The method also includes the step of: in order to derive the non-modulated carrier level at the ADC output to a target level, determining an offset correction. The method also includes the step of updating the gain and offset in response to a change in the signal level.
