Abstract
A system that incorporates teachings of the present disclosure may include, for example, a matching network including a tunable reactance circuit configured to be coupled to at least one of a transmitter portion and a receiver portion of a communication device, wherein the tunable reactance circuit is adjustable to a plurality of tuning states, and wherein the determination of a tuning state is based on parameters associated with a detected interference. Additional embodiments are disclosed.
Claims20
A method comprising:
- measuring, by a system including a processor, parameters associated with forward and reverse power during a transmission burst and between transmission bursts, wherein the system is integrated in a communication device;
- comparing, by the system, at least a portion of the parameters to a threshold;
- determining, by the system, whether the parameters are valid or invalid based on the comparing;
- adjusting, by the system, a tunable reactance circuit of the communication device to a first tuning state according to the parameters responsive to a determination that the parameters are valid;
- and
- adjusting, by the system, the tunable reactance circuit to a second tuning state responsive to a determination that the parameters are invalid, wherein the second tuning state is a last known tuning state for a use case of the communication device that was previously determined valid.

A method comprising:
- detecting, by a system including a processor, an existence of an interferer, wherein the system is integrated with a communication device;
- determining, by the system, a tuning state for a variable matching network of the communication device based on whether the interferer exists and based on parameters measured from a feedback configuration;
- adjusting, by the system, the variable matching network based on the tuning state when the interferer does not exist;
- and
- adjusting, by the system, the variable matching network based on a previously determined tuning state when the interferer does exist.
