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.
