CURRENT REDUCTION BY RECEIVER LINEARITY ADJUSTMENT IN A COMMUNICATION DEVICE

摘要

A method for reducing current drain in a communication device includes a step (404) of determining when the communication device is transmitting. A next step (408) includes lowering the current level to the receiver when communication device is not transmitting. A next step (406) 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.
