ABSTRACT:
A method and apparatus is disclosed for improving performance of a communication receiver. In one embodiment a method and apparatus is configured to process a communication signal by adjusting the amplification level of the signal and monitoring for a corresponding change in the error rate which indicates the increased error rate is caused by an interference or jammer signal. A method and apparatus is disclosed which reduces the error rate if the error rate can be reduced by activating error reducing operations. In one embodiment current flow to a mixer is increased to reduce the error rate. The apparatus may be further configured to periodically monitor the error rate during periods when error reducing operations are active. If the monitoring determines the error rate has sufficiently decreased then the receiver operation is restored to normal operation. Phase offset adjustment may also occur to further reduce the error rate.
