A method for reducing current drain in a communication device includes a
step of determining when the communication device is transmitting. A next
step includes lowering the current level to the receiver when
communication device is not transmitting. A next step includes raising the
current level to the receiver when communication device is transmitting.
Changing the current level alters the linearity of the receiver. As a
result, the communication device reduces power consumption while operating
in a traffic channel. The system is applicable to full duplex systems such
as code division multiple access (CDMA) systems.
