A method to reduce crossmodulation in a multimode radio communication device
with
a transmitter, a receiver, and a second receiver (400) that operates in
a receiver channel bandwidth (402) includes a step of measuring a first
signal strength in the receiver channel bandwidth (404), a second signal
strength outside of the receiver channel bandwidth (406), and a power level
of the transmitter. A next step (408) includes determining a signal-to-crossmodulation
interference ratio (SCMIR). A next step (410) includes calculating a SCMIR
threshold. A next step (412) includes comparing the ratio to the threshold.
A next step (416,420) includes increasing the linearity of the receiver
if the ratio is less than the threshold.
