Accordingly, a system and method are provided for adaptively controlling amplification in a wireless communications device receiver. The method comprises: receiving a signal with a variable signal strength; amplifying the received signal in response to the signal strength, to supply an amplified signal. More specifically, amplifying the received signal in response to signal strength includes selecting a gain state in response to a plurality of signal strength switch point. The method further comprises: measuring signal quality; measuring signal energy; and, modifying a relationship between receiver performance and amplified signal strength, in response to the measured signal quality and measured signal energy. Other aspects of the method comprise processing the amplified signal, so that a processed signal quality and processed signal energy can be measured. Then, the relationship between receiver performance and amplified signal strength is modified in response the processed signal quality and the processed signal energy.
