Abstract

A radio receiver has a low noise amplifier. The low noise amplifier is enabled. If a predicted level of interference is expected to produce an acceptable bit error rate or other signal error measurement, the low noise amplifier is set to a "low" linearity level. If the predicted level of interference is not expected to be acceptable, the low noise amplifier is adjusted to a "high" level of linearity. The level of linearity required is determined by checking one or more prediction criteria: the mobile station's current operating mode, the strength of a received signal, the strength of a signal transmitted by the mobile station, the current level of interference, an acceptable level of interference, and whether the low noise amplifier is enabled or bypassed. Each of the prediction criteria may not be weighted equally. The determination is repeated as the prediction criteria change.
