Abstract:
A system that incorporates teachings of the subject disclosure may include, for example, method for initiating a mode of operation of a communication device, measuring a signal to determine an adverse operational effect on the communication device, determining a tuning state from the signal to compensate for the adverse operational effect, tuning a circuit of the communication device having a variable reactance according to the tuning state, storing the tuning state in a memory of the communication device, and tuning the circuit according to the tuning state retrieved from the memory responsive to detecting a reoccurrence of the mode of operation of the communication device. Other embodiments are disclosed.
